Getting Really Ugly

I'd say the gloves are off in John McCain's Senate primary race against wingnut J.D. Hayworth...

The campaign of Sen. John McCain (R-AZ) has a new Web video making fun of former Rep. J.D. Hayworth (R-AZ), who is challenging McCain in the Republican primary, over Hayworth's mistaken insistence last week that the United States never formally declared war on Nazi Germany during World War II.

"J.D. Hayworth," the announcer says. "Is it any wonder he was voted among the dumbest members of Congress?"
