WASHINGTON - Republican Senate leader Mitch McConnell appears to have eked out a narrow victory for re-election in Kentucky as several of his colleagues fell to Democratic challengers.

Television networks projected that McConnell would win another term despite a fierce challenge by Democratic businessman Bruce Lunsford.

McConnell became a top target in 2008 after Republicans knocked off the Democratic leader Tom Daschle in 2004. President George W. Bush called McConnell this evening to congratulate him on his victory.

Meanwhile Republicans are projected to hang on to seats in Maine and Georgia as well.  Democrats have already won Republican seats in North Carolina, Virginia, New Hampshire, and New Mexico so far.  Still unknown are Senate races in Minnesota, Colorado, Oregon, and Alaska.

Democrats are hoping they can reach the magic number of 60 which would enable them to bypass procedural hurdles from Republicans.
