...He'd have to tackle DeKalb County CEO Vernon Jones in the Democratic primary.

Georgia is a state where African-Americans make a majority of the voters in the Democratic primary.  I think it would be a considerable challenge for Jim Martin to defeat Vernon Jones.

But who knows.

Jim did 3% better than Mark Taylor, our Gubernatorial nominee.  He still lost by more than 10 points.  In fact, he did about the same as our SOS nominee and no one is clamoring for her to run.

I expect that Democratic fundraising coffers nationwide will open wide for whoever runs against the shameful Saxby Chambliss.

from the Democratic party chair for this district. He seems to think that it's a pretty sure bet, and he would be the one doing the recruiting, so he should know.

Jim Martin was a very good candidate. I would love to see him run. I don't know if he'd be able to make it against Vernon Jones though like Andre says. Of course, Vernon Jones is sure loser against Chambliss.

There is no way Martin will beat Jones in the Democratic primary here. Black voters like it or not vote for the African American candidate. Its not exclusive to the presidential race. Poor Steve Cohen in Memphis is also feeling the sting of this

I like Hillary (though I don't like her campaign), but if Hillary's at the top of the ticket, Martin won't have a chance in hell of beating Chambliss, and we'll almost surely lose John Barrow and Jim Marshall's seats.  There are better chances to unseat Chambliss with Obama, but admittedly not much better.  Chambliss is pretty popular.  With Obama at the top of the ticket, I think Jim Marshall and John Barrow hang on to their seats (though Marshall doesn't deserve his seat).

Hillary is as toxic as Jane Fonda in Georgia.  She'll rally Republicans even more than the specter of a changed state flag.  It'll be very, very ugly for the Democratic party in Georgia.  Edwards would have been best for the party here, but Obama will motivate young voters--both white and African American (and hopefully Latino too)--and African American voters in numbers greater than Hillary.

What kind of coattails would HRC have on the top of the ticket in Georgia?

If Obama is on top of the ticket...I could see a sliver of hope in Georgia..otherwise,forget it.

Sorry to throw cold water on this idea, but Jim Martin would not be a viable candidate to oppose Chambliss.  Jim's a good man and one of the most decent people I've ever seen in elective office but, as he showed in his 2006 campaign for lieutenant governor, he doesn't really have the charisma to run an effective statewide race.  He's more of a thinker than an emoter, and too cerebral to appeal to the average Bubba out in the rural stretches of the state.  

If Martin could somehow win the primary against Vernon Jones, which he probably wouldn't, he still would lose to Chambliss by about 10 points, I would estimate.

To really give Chambliss some opposition, you're going to have to find someone with deep pockets who's willing to give Jones enough money to exit the race. Then you'll have to persuade someone who DOES have the ability to run statewide, like Roy Barnes or DuBose Porter, to get into the race.  I don't see any of that happening, frankly.
