GOP Inconsistent?

People have been saying that Republicans are demonstrating bias or at least being inconsistent by saying Craig should resign but not making the same demand on Vitter, that they regard homosexual infidelity differently than they regard heterosexual infidelity. They may be right. After all the GOP has not made any great effort to makes friends from non-heterosexuals.

But, in all of the commentary I have read and heard, I have not run across anybody who has noted that a Republican would appoint Craig’s successor and a Democrat would appoint Vitter’s. And partisanship often trumps consistency or principle.
