Congressional Republicans are marginally more popular and significantly less contagious than the swine flu. Even conservatives are keeping their distance. House leader John Boehner’s perpetual tan has become a presidential punch line. Senate leader Mitch Dr. No McConnell is known only for obstruction. Ideologues like Rush rush to fill the leadership vacuum, seeking to purge the party of any lingering moderates. It’s gotten so bad that neo-con Bill Kristol suggests that leading presidential candidates for 2012 might well be the oft disgraced Newt Gingrich and..gulp.. Darth Cheney himself.
