What's with Republicans gay-bashing Edwards?

First Ann Coulter's inner foulness got the better of her and she called Edwards a fag. Now Huckabee is calling him a pussy:

“We've had a Congress that has spent money like Edwards at a beauty shop,” Mr. Huckabee said to roars of laughter at the allusion to Mr. Edwards’s paying $400 for a haircut. (Terror Attack Scenario Exposes Deep Differences Among G.O.P. Hopefuls -- May 16, 2007 -- New York Times)

When Bill Clinton got nailed for his pricey haircuts ten years ago, nobody used the word "beauty shop," to the best of my recollection. The way the Republicans are harping on this Edwards-is-a-homo theme you'd think they were actually afraid of him.
