One of the unanswered questions after John McCain's stunning loss to Barack Obama Tuesday night remains whether his decision to appoint an unknown, relatively inexperienced, obscure state governor as his running mate contributed to his downfall. Speaking to reporters in Arizona, Alaska Gov. Sarah Palin said she was "sorry" if she cost John McCain any votes, and she demurred when asked whether she plans to run for president in four years. Also said in this video: "Right now I cannot even imagine running for national office in 2012." This video is from MSNBC's News Live, broadcast November 5, 2008.
