Romney To Air New Ad on Tax Pledge

Coinciding with his recent attacks on Rudy Giuliani's economic record, the AP is reporting that Mitt Romney will begin airing a new ad on Romney's promise not to raise taxes.

In the ad Romney says "For years, conservative candidates for president signed their name on the dotted line, pledging to oppose tax increases. I'm proud to be the only major candidate for president to sign the tax pledge. The others have not."
