Mollohan's coverage on CNN.com

Reading over CNN.com story about Mollohan, I was struck by this paragraph:

While Mollohan's troubles threaten to become a major campaign problem for Democrats, Pelosi, of California, said in a statement that Mollohan decided on his own to step down and that she accepted his decision.

Oh really?  Mollahan's troubles were going to be a MAJOR problem?  For ALL Democrats?

I know it's a small issues, but after reading this quasi-love letter to Rove, it just makes me think, "what are they talking about?"  If ONE Democrat with problems is going to be a major issue for other Democrats, how will the numerous Republicans with legal problems affect all the other Repubs?
