How would he get off the hook three or four times from the left? That's a Republican specialty. Ask Scooter, Ask Gonzales, Ask Ted Haggard (although not a politician, a staunch [hypocritical] Republican. Ask Newt -- "oh Lord, I have sinned! I now need forgiveness to restore my political career as I run for President."
Ask Speaker J. Dennis Hastert (whom the Republican party would not censure) - unlike the 1983 affair with Gerry Studds (Dem). He was the first openly gay national politician in the U.S. In 1983, he admitted to having had an affair with a 17-year-old page in 1973 and was censured by the House of Representatives. The Democratic leadership stripped Studds of his chairmanship of the House Merchant Marine Subcommittee.
No, the immoral Republican party specializes these days in that kind of "get out of jail free" bullshit. Cheney and Bush supposedly not part of the Executive Branch? How do they get away with that crap?
Republicans weren't always so misguided. But with Ronald Reagan -- No, make that Nixon -- and increasingly after (except for Gerald Ford), the Republican party lost its way.
