I just find it interesting that a unknown Canadian nobody has the nerve to question the "credibility" of heavy hitters such as Rush and Mark Levin, and do it to his face no less. I love watching Mark on Hannity and Colmes, but are you really saying that none of us here should be allowed to question his posts?
I generally agree with Mark, but I don't think any of us is infallible and I think sometimes Mark goes a bit overboard on the rhetoric - as do many of us, from time to time.
At least you're an American and you realize Mark's great contribution to our country. Critique all you like.
Compare your statement to that annoying half pinko Canadian's and you'll see a big difference.
