A new Survey USA poll shows Democrat Jim Martin trailing Chambliss 44 percent to 46 percent. Chambliss's lead is insignificant since the poll's margin of error is 3.8 percent. Martin, a former state legislator and candidate for lieutenant governor, had trailed Chambliss 36 percent to 53 percent in a Survey USA poll two weeks ago.
