If you're heard Sen. John McCain's radio ad attacking J.D. Hayworth, you know it featured a creepy woman whispering about how rotten the former congressman for funding fruit-fly research and snake eradication in Guam.

Hayworth is taking a more humorous approach with his first video ad. It kind of matches Hayworth's approach so far: Saying nice things about McCain even as he tears him down. The message: McCain is a nice guy who served his country, but it's time for Arizona to have a consistent conservative.

When he lost his congressional seat in 2006, J.D. tried to use a hammer against Democrat Harry Mitchell; in this race, he's starting out with a scalpel.
