I view him as a distraction who is undermining support for America and the WOT. He distracts many principled people and demoralizes others. And his association with Holocaust deniers is a moral flaw. Some people deserve to be shunned, and Ron Paul’s unwillingness to shun them puts him in that category.
Presuming he establishes his credibility, which he hasn't.
I think he's largely a non event, but a distraction.
