The Romney campaign has just released a new TV ad to air in New Hampshire starting today. We’ve documented the various negative attacks against Huckabee in Iowa and now McCain in NH from Mitt’s folks via TV and web advertising. But the new ad is something different. As the title blatantly notes, the ad is decidedly positive in tone and focuses on economic growth and the need for America to “go forward” - themes that are perfectly crafted for Romney. Whether this kind of ad (part of Mitt’s new strategy to stop attacks against Huckabee will drilling McCain) will work in New Hampshire with the primary just days away is yet to be seen.
