Sen. Lisa Murkowski has conceded to attorney Joe Miller in Alaska’s Republican Senate primary. This makes her the third incumbent Senate victim of the 2010 primaries, after Sens. Bob Bennett, R-Utah, and Arlen Specter, D-Pa.

In the House, Reps. Alan Mollohan, D-W.Va., Parker Griffith, R-Ala., Carolyn Cheeks-Kilpatrick, D-Mich., and Bob Ingis, R-S.C., have all fallen to primary challengers.
