Obama's Super Tuesday Surplus (What the National Polls Aren't Telling You)

Cross-posted at One Million Strong

Whoever wins Iowa will get a huge bounce. So, for those of us who support Barack Obama,
the latest ABC News/Washington Post Iowa poll -- which showed Obama with a 4-point lead --
is very good news.

But a win in Iowa will matter for Obama only if -- at the very least -- he has sufficiently closed
the gap in enough of the subsequent early and Super Tuesday states for an Iowa bounce to make
a decisive difference. In a critical mass of those states, an Iowa bounce for Obama would have to
be greater than any remaining lag between Obama and Clinton.

Now comes evidence that, in fact, Obama lags significantly less in the Super Tuesday states
than he does nationally
-- that Obama could be setting the stage for a Super Tuesday sweep on
the heels of an Iowa victory.

According to Rasmussen, Obama is a statistically significant 6 points closer to Clinton in
the Super Tuesday states than he is nationally.

Chris Bowers at OpenLeft has the whole story. Here's the relevant excerpt (emphases mine):

In my Nomination at a Glance tables, I have used Pollster.com's national poll regression
lines...as a substitute for comprehensive...Super Tuesday polls. Lacking comprehensive
polling for the twenty or so states that would take place on Super Tuesday, I figured that
national polls probably were not really all that different from such a wide swath of the
country, anyway. However, new data from Rasmussen Reports indicates that might
not actually be the case. Here is Rasmussen's data on the February 5th states, with
national numbers in parenthesis:

Super Tuesday, Democrats
Clinton 41 (41)
Obama 23 (17)
Edwards 14 (14)
Richardson 5 (5)
Biden 3 (5)
No one else above 2%

Apart from Obama's better position on February 5th compared to his national numbers,
a difference which is statistically significant, there are no real differences. However,
the Obama difference is important, since it further emphasizes that he will
almost certainly win the nomination if he sweeps Iowa and New Hampshire.
Wins in those two states will probably allow him to gain much more than 18%
on Clinton
, especially since he is facing a smaller deficit in South Carolina.

Obama Gains 6 Points on Super Tuesday

Compared to the national numbers, everybody else -- Clinton included -- is flat (or loses).

I think it's a stretch

to say he will almost certainly win the nomination if he wins Iowa on Jan. 3 and NH on Jan. 8. There are four weeks between then and Super Tuesday--that's a lot of campaign time and a lot of media cycles.

Four weeks
...won't look so long, if South Carolina tilts for Obama, too.

Not to mention...

...the X factor of an Edwards withdrawal after an Iowa loss.

by horizonr 2007-11-25 06:17PM | 0 recs
And...

...Rasmussen's Super Tuesday gap today is 6 points less than the national gap. Chances are that both
the Super Tuesday gap and the national gap will narrow even further between now and January 3 --
meaning that Obama will not need the 18-point bounce that Bowers contemplates.

Re: And...

You are wrong.  There is NO such 6% Super Tuesday gap.

Re: Obama's Super Tuesday Surplus (What the Nation

I think for us Democrats, the showdown is going to be SC and FL; especially if Clinton loses both IA and NH; because her support will sustain until that latter time.

If you think the nominee (whoever it is) isn't going to seat the Florida delegates, you're kidding yourself. Even Howard Dean says that the Florida delegation will most likely be seated.

With all due respect...

Chris Bowers's analysis here is total crap.  He's comparing with the latest Rasmussen national sample, which has Obama at 17.  That's signficantly below the most recent trending, which means it's most likely an outlier from an ugly polling night.

Obama's national number in recent Rasmussen polling has been...averaging right around 23.

Sorry, no real story here.

Re: With all due respect...

I agree that Rasmussen's national average for Obama looks low -- which, of course,
could mean that its Super Tuesday number is low, too.

The point is that the Rasmussen polling universe is showing a 6-point difference between
Obama's national and Super Tuesday averages.

The real question, it seems to me, is whether other polling universes would confirm that
Obama is more competitive on Super Tuesday, with other candidates flat or worse in
comparison to their national numbers.

Re: With all due respect...

No, it does not.  I posted below a very easy method to find the correct data from the same polling universe (same exact 14 day time frame used in Rasmussen's 20-state parse) and the result is that there is a ONE percent differential between the Feb. 5 states and overall national data.  ONE percent is not "showing a 6-point difference between
Obama's national and Super Tuesday averages."

It just isn't.  The evidence is crystal clear on that one.

Re: With all due respect...

Wow, and he is relying on a small daily sample. That's malpractice, he knows better. Thanks for the catch, I glanced at his post but did not check the numbers.

I can only conclude that his desperation for Clinton to lose has overwhelmed his integrity. He is looking for any way to make it look like Obama has momentum, no matter how specious, in a pitiful attempt to impact the primary.

Re: With all due respect...

CLinton's support is name recognition in all states other than the ones where people have campaigned. She'll crash and burn if she loses her aura of inevitability. It'll be hilarious!

Read the Polls

Obama has registered 17%-26% in the last week in Rasmussen's Daily Tracking poll, so you are hyping this way too much.

Source: http://www.rasmussenreports.com/public_c ontent/politics/election_2008__1/daily_p residential_tracking_polling_history

Interestingly, when you average the last seven days, you get 23.5%. Not too far off from Rasmussen's Super Duper Tuesday poll.

Re:

For crying out loud, what a bit of shoddy research on Chris Bowers' part.  There is absolutely no story here, as rashomon correctly pointed out.

Let's look at the evidence.   So, this 20 state "special" was taken from 2 weeks' worth of daily tracking data, as stated in the article, so an apples to apples comparison would have to be between the results listed and the EXACT SAME 2 week's worth of NATIONAL tracking data from the same time frame, right?

http://www.rasmussenreports.com/public_c ontent/politics/election_2008_1/2008_pr esidential_election/in_february_5_states _clinton_and_giuliani_still_on_top


Data from the Rasmussen Reports daily Presidential Tracking Poll shows New York Senator Hillary Clinton attracting 41% of the vote in the twenty Super Tuesday states. Illinois Senator Barack Obama trails Clinton with support from 23% of Likely Primary Voters in those twenty states while John Edwards is the top choice for 14%. New Mexico Governor Bill Richardson is preferred by 5% while Delaware Senator Joe Biden attracts 3% support.

These results are based upon survey interviews conducted for the two weeks ending November 21.

So, let's look at the 2 week's worth of NATIONAL tracking data, backtracking from Nov. 21 to Nov. 08, exactly 2 week's worth of data:

http://www.rasmussenreports.com/public_c ontent/politics/election_2008_1/daily_p residential_tracking_polling_history

Taking the trusted ol' calculator out you just add up all the numbers compiled by Clinton over those 14 days, then divide by 14 to get your data. Do the same for Obama and Edwards.

For Clinton I calcualted 41.85%, for Obama the number was 21.42%, Edwards' number is 14.71%.

Result:

Clinton 41.85%
Obama 21.42%
Edwards 14.71%

I guess you can round up, so a more "readable" horse race shows up.

In the end, for the national race, taking the exact same polling data that was used to parse down to the 20 Feb. 5 states, you get


Clinton: 42%
Obama: 22%
Edwards: 15%

The Feb. 5 states showed, as per the article:  

Clinton: 41%
Obama: 23%
Edwards: 14%.

No story.  Why in the world would Bowers not compare the EXACT SAME polling reference frame (2 weeks) from the EXACT SAME national polling data readily provided for apt comparison, instead decided to take a snapshot of a WEEKLY poll collecting SEVEN DAYS worth of data that ended collecting data on 11/17/2007?  It just makes no sense at all.  I am used to much better from Bowers.

The real news contained in this Rasmussen poll is that Clinton is exactly as  strong in the Feb. 5 states as she is nationally, which is something that was denied previously on this site.   It is clear:  National polling aggregates = The twenty February 5 states.  

One additional important thing to note about this is that in many Feb. 5 states Independents are not allowed to participate, and since we know how much better Clinton does amongst DEMOCRATS when compared to her showing amongst INDEPENDENTS, her lead in the Feb. 5 states which don't allow Independent's participation is bound to be at least 5% higher than this data suggests.

What that tells me is this:

If Clinton wins just a couple of states out of the first 6, it is all over but for the crying.  

For instance, even if Clinton loses Iowa but then takes at least 2 states of the first 6, she should win a vast majority of the Feb. 5 states with ease.  2 or 3 states won would neutralize any Iowa/NH effect in this polling data we are seeing here, would effectively freeze these results at approx. 20% cushion (more in states that don't allow Independent's participation.) That is especially true if those are important states like Florida, Michigan, and Nevada, which all 3 appear to be impenetrable firewalls that Iowa and/or NH won't be able to shake around to the extent needed to turn 25%, 25% leads (in the case of Edwards) into wins for someone else.   Note: Michigan will more than likely go to Clinton due to the fact that aside from Dodd she is running unopposed in that state

Nobdoy really knows what is going to happen in Iowa, but what we do know is that this is a shoddy diary with an even shoddier conclusion and premise.  But in this case I don't fault horizonr, more Chris Bowers.  Although horizonr COULD have seen the writing on the wall that this was one lazy bit of research and looked at the data himself.  That we can fault him for, as nothing beats conducting your own research, especially when the necessary data to make a true one-on-one comparison is right there at your fingertips.

Re: Obama's Super Tuesday

If Obama wins Iowa and NH , i believe he'll win S.C and i strongly believe Obama will not lose this nomination if he wins 3 early states....Sorry.

Right now , Obama has to keep it into the single digit in NH...If he can keep Hillary from opening up a huge lead in Nh , then manage to win Iowa , i believe he will get a HUGE boost  since NH will be voting in 5 days and Hillary wont have time to settle to fight off the bounce.

South Carolina will be in Obama's backpocket after 2 big wins in whitish state...Black people will be convince that he can win after defeating Hillary back to back in states that do not even have many black voters.

With 3 early state victory , i believe Obama will zero in on midwestern states like CO , MO , AZ , UTAH , NB , ND and his home state of IL + southern states with huge black population like GA , MS , AL , NC , TN....Hillary will probably lock up the northeastern states.

Then , the big fight will be in California where Obama could count on about 11% black voters , but Hillary could win the state since she has the CA machine behind her...I still believe Obama will end up winning it tho.

Re: Obama's Super Tuesday

SC will be well after Nevada and Michigan go to the polls.  Michigan will be mostly a media event, but it will get a lot of coverage, nonetheless.  Then you have Florida following SC.  Florida by itself dwarfs any state preceding it strongly in terms of state's importance.  No delegates to be awarded, but the Florida results will get huge media coverage, and are the last state primary before Super Tuesday.    

If Clinton manages to win just 2 of the early states (IMHO she'll win them all, but for argument's sakes,) she'll keep these 18% to 22% margins for Super Tuesday we are seeing here.  Nevada is really key (she leads that state with huge margins) but Florida as the last state before Super Tuesday will also be hugely important to show Super Tuesday states the way.

Re: Obama's Super Tuesday

If he wins IA and NH. I would say that's a pretty big if. The fact is he has to be a head of Hillary come Super Tuesday. If everything is even or Hillary is ahead he doesn't have a chance. The only Super Tuesday state he can count on is Illinios.

How can anyone predict the size of a bounce?

Especially in a year with a new calender.

Re: Obama's Super Tuesday Surplus (What the Nation

Like it or not, based upon historical analysis of presidential primary polling over the past 20+ years. the winner of Iowa can expect a 15 point bump in the NH polls. This enables the winner of Iowa to win NH --or do so well that they are perceived as a come from behind winner.

Obama is within the margin in NH polls so a 15 point bump would allow this outcome.

All Chris is saying is that an 18 point bump for Obama in nat'l polling is the least you might expect to see if he wins Iowa and wins or is a close second in NH.

Like it or not this is common wisdom.

Re: Obama's Super Tuesday Surplus (What the Nation

That CW is a blanket statement and includes cycles in which four relatively unknowns duke it out.   Or 2 candidates are in the game, with one "incumbent" and one challenger who really should not be there in the first place (i.e. Gore vs. Bradley, president Carter vs. Ted Kennedy.)  

A race with candidates like these we have here with the amount of interest this race has generated and the type of professed already solidly "committed support" we have seen particularly for Hillary Clinton in states like NH will have much lower volatility coming out of Iowa SHOULD she lose a close race.  Perhaps 3% to 5% movement, which doubled amounts to a 6% to 10% poll movement.   IMHO Obama or Edwards need to be close, in solid low single digits, in NH to make any positive Iowa results have a parlay effect.

Re: Obama's Super Tuesday Surplus (What the Nation

Like it or not, based upon historical analysis of presidential primary polling over the past 20+ years. the winner of Iowa can expect a 15 point bump in the NH polls.

The last 20 years represents five elections.  Any statistician will tell you that five events is not a large enough sample to make reliable predictions from.  And it's even less reliable when conditions from one election to the next are so different (different dates, different candidates, different national moods).
