I don’t think the American people were fooled. I think he reflected the majority’s depravity, and therefore they liked what they saw in him. Evil people vote for evil leaders.
You're definitely right about a segment of the electorate who foisted Obama on us -- specifically the Planned Parenthood feminist types. Those harpies ARE downright evil, but I think they're a tiny minority of voters.
Most Obama voters I think were naive folks who thought that by electing Obama, they would "become a part of history."
I also heard some Obama voters (including Don Imus apparently) express sentiments along this line:
That by electing Obama, America would be absolved of all its guilt over slavery, and that we would now move forward into a glorious new "post-racial" era.
Of course, just the opposite happened. What I wonder is, have these voters learned anything from the last 7 disastrous years?
