Super PAC de Santorum compra medio millón en anuncios en WI

POLITICO.com:

Mitt Romney no longer has the Wisconsin airwaves to himself, but he still has a nearly 4 to 1 advantage over Rick Santorum in the last week of the primary campaign, according to sources tracking the air war.

Romney's campaign and the super PAC Restore Our Future are spending a combined $1,917,764 over the next seven days, including $742,928 from the campaign and the balance from ROF. The pro-Romney super PAC is the only group on the radio in Wisconsin and has a major TV presence across the state.

Santorum's campaign is not on the air at all at the moment, so the TV campaign is being carried by the Red White and Blue Fund super PAC. That group is in the process of putting $513,000 into the state for the home stretch.

That's a solid upper hand for Romney, though an improvement for Santorum over last week, when he had essentially no presence in paid advertising. Over the course of the contest in Wisconsin, pro-Romney forces have spent about $3.2 million to the Santorum camp's $568,000, for a roughly 6 to 1 Romney advantage.
