The Obama bump in Georgia and its possible effect on another Democrat emerging to challenge Sen. Chambliss this year.

From the AJC's Political Insider:

Since Super Tuesday, the Democratic Senatorial Campaign Committee in Washington has gone back to a number of Senate races that had been written off as unwinnable. The race in Georgia is among them.

On Feb. 24, the DSCC completed a four-day poll of 600 likely Georgia voters that measured Chambliss’ vulnerabilities. The survey found:

— The Republican incumbent led when pitted against a generic Democrat, but only by 42 to 37 percent;

— Only 38 percent of those surveyed rated Chambliss’ performance in office as good or excellent. Forty percent rated it fair or poor — perhaps a result of the Republican senator’s involvement in an attempt at immigration reform last summer;

— And only 37 percent of voters would commit to re-electing Chambliss.

Both Democrats and Republicans have told us these weaknesses are not particularly news, but have been overshadowed by Chambliss’ fund-raising efforts, and by the weakness of the Democratic field.

The significance is that such polls are often produced when national parties have a potential candidate — or multiple candidates — they’d like to lure into a particular race. This may be the case when it comes to the Georgia contest.

“There are people who are still considering this race,” said state Democratic party chairman Jane Kidd on Friday. “If anyone else does decide to get in, it probably will happen in the next 10 days to two weeks.”
