You just made me burst out laughing! That was a zinger!
Only half joking though. I think the media would cover them. It might be effective. People might leave Rudy in droves. Personally I think they'd be covered as bunch of right wing lunatics. And since, fortunately I think, they don't promote a candidate, the only damage would be to push undecided to Rudy. Or perhaps to the Dems, not wanting to be aligned with right wing lunatics.
I'm sure the anti-Rudys would disagree. It would be an interesting test. If they don't disagree, then the strategy here should be rethought. Because it's not sapping support for Rudy, in fact it's moving people toward him out of resentment.
