Good news and bad news for Senator Saxby Chambliss: A new poll shows his lead at six points, higher than several earlier surveys, but the Republican is still well below 50%. The Mason-Dixon poll for NBC News surveyed 625 likely voters 10/22-23 for a margin of error of +/- 4%. Chambliss, ex-state Rep. Jim Martin and Libertarian Allen Buckley were tested.

General Election Matchup
(All / Dem / GOP / Ind / Wht / Blk)
Chambliss...45 / 14 / 77 / 36 / 59 / 12
Martin......39 / 75 / 8 / 38 / 23 / 78
Buckley..... 5 / 2 / 4 / 12 / 6 / 1

Increasingly, it looks like Martin's chances of winning depend on a high African American turnout and a decent performance for Buckley, who has run several times before. But if no one gets to 50%, the top two finishers will head to a December runoff.
