Sen. John McCain (R-Ariz.) is up with a new TV ad that hits his primary rival on spending. The slow, somewhat monotonous spot says former Rep. J.D. Hayworth (R-Ariz.) is an "avid earmarker." It then scrolls through a list of House bills Hayworth supported "before we voted him out of office," says the announcer. 

McCain generated some unwelcome buzz a couple weeks ago with the release of his "danged fence" spot.

The new 30-second spot is airing statewide on broadcast and cable. Fred Davis of the firm Strategic Perception Inc. is producing McCain's ads.
