Some of Obama's volunteers are coming to Georgia:

Martin continued to tie himself to President-elect Barack Obama in new television ads. His campaign has invited Obama to come to the state to campaign for the Atlanta attorney and former state lawmaker. Martin’s campaign is also using Obama’s ground troops in the runoff to get out the vote.

Obama’s former campaign workers are now assisting Martin in his 25 offices across the state, Martin said. Those ground troops, he said, are more important than big-name politicians for getting voters back to the polls. Some prominent Democrats have volunteered to come down for his campaign, Martin said, without offering specifics.

He has to excite the base of the Democratic Party and by getting Obama involved, either directly or indirectly, could do that. It also could motivate Republicans, many of whom are disgruntled with Chambliss, to get out and vote.

Oh, and while John McCain is coming to Georgia to help Chambliss, Sarah Palin is not.
