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

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.
