Well, Vitter is still a sitting senator. And he's running for re-election in November. What's more, he could very well win. A Rasmussen poll currently shows Vitter holding an 18-point lead over his likeliest Democratic opponent, Congressman Charlie Melancon, in Louisiana's race for the U.S. Senate.
And guess what? Vitter is still touting "family values." Indeed, he still sees himself as a paragon of virtue.
While other hypocritical GOP politicians (from Larry Craig to Mark Foley) have been forced from office, Vitter continues to hold his Senate seat. As far as he and his followers are concerned, the past is the past.
As Vitter said in a 2007 statement: "This was a very serious sin in my past for which I am, of course, completely responsible. Several years ago, I asked for and received forgiveness from God and from my wife in confession and marriage counseling."
It's a shame, though, that GOP hypocrites like Vitter were never willing to forgive the sins of other people, like Bill Clinton. (Oh, and the last time I checked, having a mistress isn't illegal, but prostitution is).
Recall that in 1998, Vitter called on Clinton to resign for having an extramarital affair.
