Whither Vitter?

It's interesting, with all the excessive media attention on Democratic congressman Weiner, and whether he should resign, that no one in the media is asking why Republican senator David Vitter, who paid numerous prostitutes for kinky sex (he reportedly liked them to put diapers on him) was never forced to resign. Fair is fair. If a congressman who virtually cheated on his wife, and broke no laws, should resign, then what about a "family values" Senator who actually cheated on his wife, repeatedly, with prostitutes, and broke the law?

At the very least, the media should be asking Republican leaders why the double standard? They should be asking David Vitter himself.
