Georgia Democrat Jim Martin blasts Sen. Saxby Chambliss (R-Ga.) for voting against Sen. Jim Webb's (D-Va.) 21st Century G.I. bill in his latest TV ad.

Martin, a Vietnam veteran, has hit Chambliss for numerous veterans-related votes this week. Yesterday, in a Thanksgiving video message circulated by Martin's campaign, former Sen. Max Cleland (D-Ga.) criticized Chambliss for voting against more leave time for soldiers serving in Iraq and Afghanistan.

Martin and Chambliss will face each other in a Dec. 2 runoff for Chambliss's Senate seat. See the new ad below.
