Vitter should have had the deciency to just bow out of politics when he got caught with his pants down! When it comes to immorality, the GOP is as bad as the RATs. Republicans have to clean up their acts. We cannot have people with no morals for our leaders any longer.
Had Vitter done that, it's quite possible that Bush would've signed an amnesty bill near the end of his second term. Politics is ugly business, always has been.
