NO, they didn't. BHO was elected because the other guy was McCain and BHO LIED to the populace about his agenda.
It's true that McCain was one of Obama's most enthusiastic supporters.

The American people were so intoxicated with the euphoria of electing a Black President and the hope of ending racism and racial discrimination once and for all that they were intentionally blind to everything else--which, of course, was stupid and dispelled once and for all any notion I ever had of "the inherent genius of the American electorate".
