John Ensign and His Affair

Sen. John Ensign (R-NV) announced on Monday that he had an affair with a campaign staffer, Cindy Hampton, also of Las Vegas. http://www.lvrj.com/news/48421902.html
A couple of thoughts. First, John Ensign is a pig for the affair. What he did was wrong and unethical by having the affair. Ensign has apologized to his wife and apparently, she has forgiven him.
Having said that, considering who is also in the Congress, this is mild stuff. First, you have the killer of a young woman, Ted Kennedy, then you have the bathroom pervert, Larry Craig, Barney Frank who had a whore house run out of his house and the infamous former KKK member, Robert Byrd. Then you have Harry Reid who has some very questionable land dealings, Nancy Pelosi and her ethical congress, Charles Rangle and his tax problems and so much more.
I am glad Ensign took responsibility and saw his presidential aspirations shot to hell. But, it has to be kept in perspective and he should not resign from the Senate.
