One of two remaining U.S. Senate races was decided on Tuesday, with voters in Georgia choosing Republican Sen. Saxby Chambliss over Democrat Jim Martin.

The victory prevents Democrats from gaining a 60-seat majority that would have enabled them to break any filibusters. Currently, they have 56 seats, plus two independents who organize with them.

One race remains undecided. A contentious recount in Minnesota pits Republican Sen. Norm Coleman against Democrat Al Franken, who campaigned frequently on reservations in the state.

In other Senate news, Republican Sen. Mel Martinez said he will not seek re-election in 2010. He was former head of the Department of Housing and Urban Development in a period where regulations were eased to favor tribal housing.
