Vodkapundit writes an open letter to Iowans -- says it all. Money quote:

Des Moines (literally, French for “tell me about the rabbits, George”)

32 years ago, your Democratic brethren took one look at Jimmy Carter -- the worst 20th Century President bar Nixon, and the worst ex-President ever -- and declared, “That’s our man!”

Three decades later, and along comes Mike Huckabee. Same moral pretentiousness, same gullibility on foreign affairs, only-slightly-less toothy idiot’s grin. Then you so-called Republicans took a look at Carter’s clone and said, “That’s our man, too!”

Yeah -- what he said.
