John McCain says that Larry Craig should resign from the Senate because he pled guilty to a misdemeanor.
Now, of course, David Vitter is also guilty of a misdemeanor, in this case, soliciting prostitution. But you see, Vitter didn’t plead guilty, so that’s completely different.
The fact that Vitter’s crime involved heterosexual sex, and that his state has a Democratic governor has absolutely nothing to do with it. If he had pled guilty, then he’s out; if he merely admits to guilt, than it’s okay. This is what is known as a “moral values” issue.
