Huh?

I read the Los Angeles Times today and came across a letter which stated the following in regards to Elliot Spitzer's sex scandal: " He should follow the example of David Vitter and Larry Craig" . I did some checking and I wonder what the letter writer meant. Vitter and Craig, both Republicans, are still Senators. Still in office and still doing as they please. Elliot Spitzer resigned today showing once again who the real party of ethics is.
