Insider Advantage broke the story.
Former state Rep. Jim Martin, his party’s candidate for lieutenant governor in 2006, is now in the U.S. Senate race. Martin formally announced Wednesday, just hours before the man he hopes to challenge – Saxby Chambliss – was planning a big to-do of his own in the Capitol with Johnny Isakson, Gov. Sonny Perdue and other officials.

With Jim Martin in the race, I think the Democratic field is now broken down into three tiers:
Tier 1: Jim Martin, Vernon Jones
Tier 2: Rand Knight, Dale Cardwell, Josh Lanier
Tier 3: Maggie Martinez
Also, I don’t believe there is a front-runner and that there will be a run-off.
