Pro-Newt Super PAC to go on the air in Iowa

A pro-Gingrich Super PAC, Winning our Future, has purchased $256,000 of airtime in Iowa from Dec. 28 thru Jan. 3, according to NBC's ad-tracking sources.

But that $256,000 pales in comparison to the nearly $3 million that the pro-Romney Super PAC, Restore Our Future, has spent in the Hawkeye State so far.
