In an effort to either get revenge, or some how prove that he really isn't gay... Sen. Larry Craig (who was arrested for soliciting a male police officer for sex in an airport bathroom) and Sen. David Vitter (who has been identified as a client of the DC Madam) have proposed a Constitution Amendment defining marriage as between one man and one woman.

When asked to explain the apparent contradiction between the law they're attempting to pass and their personal behavior, both of them stated that their earlier behavior was really just research into these alternative cultures which they now feel must be banned.  Sen. Craig was merely researching what gay people are like, while Sen. Vitter decided to find out what having a relationship with more than one woman could do to a family.

Thanks to Radley for the pointer.
