Former Congressman J.D. Hayworth [aka Foghorn Leghorn] is ready to rumble down in Arizona.

J.D. Hayworth, a former Arizona congressman and radio host, formally announced Monday that’s he’s challenging Republican John McCain for his U.S. Senate seat.  [game on]

According to Hayworth: McCain doesn’t represent Arizona citizens anymore.

According to McCain:

“I don’t know what kind of support that Mr. Hayworth has. I haven’t seen much so far, but maybe I missed it. And the voters in his district threw him out in 2006, in a heavy Republican district.”

This sucker will get ugly quick.
