I believe that Rudy had prostate cancer and was forced by this to cease his campaign for the senate seat. See how polite I can be - no invective, no ad hominem, no snarling?
I knew about it; I just don't buy the excuse when so many lives are at stake.
Witness Mel Carnahan and Tim Johnson. They're not looking so good either but they didn't bow out. Democrats understand the stakes in an election; those who excuse Rudy apparently don't.
