Romney ha gastado cuatro veces más que Santorum en Wisconsin

ABC News:

Candidates and their allies have poured serious change into the Wisconsin airwaves. Romney and his allies have spent upwards of $3.1 million on TV ad buys, according to a source tracking GOP ad buys. For comparison, Santorum and his allies have spent roughly $717,000 on TV ad buys, a margin of about 4:1.

Romney and Santorum aren’t alone on the airwaves. The Super PAC supporting Newt Gingrich- Winning Our Future- made a small ad buy in the Badger state- $120,381, according to their FEC filings.

Though it’s much smaller than the amount spent in Wisconsin, the pro-Romney Restore Our Future Super PAC has also spent money in Maryland. The group has spent $436,204 on ad buys in the state, according to their FEC filings.
