Imagine, if you will, a situation where two sitting US Senators have engaged in unlawful sexual acts. Both are members of the Republican Party; both are married. One senator paid for heterosexual sex with a prostitute (and apparently has a diaper fetish, to boot); the other senator was seeking homosexual action in a public restroom.
Arguably, both senators were engaging in improper and illegal acts. Yet, only one has been stripped of his committee assignments and called upon to resign. Can you guess which one? If you guessed the one whose transgressions were homosexual, give yourself a gold star for today.
But another difference has been largely ignored by the media- the gay sex senator represents a state with a Republican governor, while the diaper aficionado comes from a state governed by a Democrat. In other words, if Senator Craig were to resign, he would be replaced by another conservative Republican. But, if Senator Vitter goes, his governor would appoint a Democrat to fill his seat.
So, for those who worry that the GOP is obsessed only with gay sex, take heart. They are equally, if not more, concerned with their ever dwindling numbers in Congress.
