What in the world is wrong with Republican candidates this year?

From the AP:

Republican Sen. Conrad Burns [R-MT], whose recent comments have stirred controversy, says the United States is up against a faceless enemy of terrorists who "drive taxi cabs in the daytime and kill at night."

Macaca? Taxi cabs? Only Christians should legislate?

At least he didn't mention convenience stores.

TOM ADDS: This is Burns' third outbreak of foot-in-mouth disease in the last six weeks. For an experienced politician, he's sure acting an awful lot like a novice.
