How did Sen. Saxby Chambliss (R) and Jim Martin (D) spend their last day of campaigning before today's runoff election? Chambliss hit four rallies with former vice presidential candidate Sarah Palin, and Martin rallied with hip-hop stars Ludacris, T.I. and Young Jeezy, as well as Rep. John Lewis, the Atlanta Journal-Constitution reports. Both were attempts to excite their base and get out the vote in what is often a low-turnout affair. From the AJC:

Chambliss and Martin crisscrossed Georgia on Monday, rubbing shoulders with celebrities and the common folk as their bitter four-week runoff came to a close.

The battle between the former University of Georgia Sigma Chi fraternity brothers could tilt the balance of power in the Senate.

Alaska Gov. Sarah Palin roared back onto the campaign trail for the first time since the Nov. 4 election, telling thousands of voters at rallies across Georgia that the state's U.S. Senate runoff is a chance to begin rebuilding a wounded Republican Party.

"It's going to take rebuilding, and I say let that begin right here in Georgia tomorrow [Tuesday] with the re-election of Saxby," Palin told 6,000 cheering supporters at the Gwinnett Center in Duluth, her last stop of a four-city campaign swing for Chambliss.

Martin ended his last day on the campaign trail at the state Capitol in Atlanta, where he was lauded by a civil rights veteran and a who's-who of hip-hop, including Atlanta-based Ludacris, Young Jeezy and T.I.

Ludacris told several hundred Democrats bundled against the cold that Chambliss was running for the wrong reasons. "He's just about politics and not about helping the American people," said the hip-hop star.
