The vilification of Nixon was up there.
And the close (stolen) election that Nixon did not contest.
A lot of the most vile hatred is coming from twentysomethings who are too young to remember Nixon and Reagan. Therefore, they will be doubly shocked (Or maybe I should say stuned) when Bush wins. Among the many other things they are ignorant of is the fact that there are a whole lot of people (Including many in their own age group) who do happen to like Bush.
