I think the Wilder Effect will be out in full force in November.
People will be so sick and tired by then.
The more the left plays the racist card the more they will energize antagonistic reaction. Lukewarm fence-sitters, who want to be fair minded, will be insulted by the implications of this attempt at intimidation and vote against Obama just to re-establish their right to vote as they see fit. To do otherwise would feel like submitting to thuggery and no American wants that.
If the 'rats keep this up they will guarantee a win for McCain, so let's by all means cheer them on.
