Vitter: It's Not the Same!!!!

With Elliot Spitzer out, what about the Senate's number one hooker-lover, David Vitter? Well:

Anybody who looks at the two cases will see there is an enormous difference between the two of them. The people that are trying to draw comparisons to the two cases are people who've never agreed with me on important issues like immigration and other things.

It's true that I don't agree with Vitter about much, so maybe my opinion doesn't count, but the difference isn't at all clear to me.
