The defections from the Clinton campaign have begun.  George McGovern, who endorsed Clinton back in 2007, has just endorsed Barack Obama!  McGovern is also urging Clinton to get out of the race.  The former Iowa Senator has been a long time friend of the Clintons since the then unmarried couple were instrumental in the Texas effort of McGovern’s 1972 presidential campaign bid. McGovern says that he will call Bill Clinton to inform him of his decision.  UPDATE:  McGovern says that he has talked to President Clinton and informed him of his decision.  The former Senator also said that he and Bill had a pleasant conversation with no voices being raised.  McGovern gives as his reason for endorsing Barack Obama the following; ”the time has come for democrats to unite and get ready for a tough race against John McCain.”  He says that he is “hopeful that Sen. Clinton will see fit fairly soon.”
