Making terroristic threats is OK if you're a Republican too

Remember when Jesse Helms said that if Bill Clinton were to show his face in Helms' home state of North Carolina, he should watch his back? No law enforcement officials said a word about that.

You can't wear an "Impeach Bush" T-shirt on an airplane, but Rep. Darrell Issa can say this to Henry Waxman on Washington Journal:

"If Henry Waxman today wants to go to Iraq and do an investigation, Blackwater will be his support team. His protection team. Do you think he really wants to investigate directly?"

...and that's perfectly OK. No, Issa isn't threatening Waxman with bodily harm done by himself, but he is saying that Blackwater security officers might retaliate against Waxman if he goes to Iraq to investigate the company -- and he seems to think this isn't a problem.
