"didn't SD just change their rules and Dashole can't run for Senate and President at the same time??" Oh that would be such a shame. Actually, he is probably doing it to save face. People will understand when he gets his @ss whupped by Bush, but if Thune mops the floor with him he will look like the pathetic, sniveling little weasel that he is.
It is becoming more likely that Janklow will run for the Senate. A primary contest between him and Thune would be a close run thing, were that to develop.
