It all started, says presidential historian David Goldberg, with John McCain's change of campaign leadership.
McCain was suddenly controlled ... not his own man any longer.
Many people pointed to the negative campaigning from the Republicans and suggested a backlash. But in remarks on News Talk Online on Paltalk.com, Goldberg noted that both campaigns were equally guilty of negative campaigning.
But Goldberg says McCain's biggest problem was George W. Bush. He couldn't separate himself from the current, unpopular president.
His choice, imposed perhaps by the Republican National Committee, of Sarah Palin as his running mate, was designed to shore up the party's conservative base, which wasn't overly enthusiastic that he was the nominee. But that failed to help him with the non-partisan undecided voters.
Had he chosen a more moderate running mate, Goldberg says, the results may not have been much different. Because some conservatives may have sat out the election, voted for Libertarian Party candidate Bob Barr, or may have even voted for Obama.
