Because calling people corrupt without actually backing it up is really quite a serious claim, and one that most sane people would ignore.
The time to back up the claims will be in 2006 while the campaign is going on.
Also, you failed to address my other point. But I'll instead assume that you don't mind if the Republicans call any New Jersey or Washington Democrat corrupt either?
Freedom of speech. Go for it.
I would prefer to see no political parties at all, so that there would be less blind partisan idiots in the world.
Well, you are definitely a Republican-leaning independent. Seems like you b*tch everytime any Democrat disagrees with or criticizes Republicans.
