TOP 10 RIGHT NOW
Mitt Romney has a new lead in Wisconsin, once Santorum country, grabbing 39 percent of the vote over Rick's 31 percent. Back in February, Santorum led Romney in the Badger State by 34 percent to 18 percent. Perhaps the increase in Mitt-mentum is a response to Romney's hike in spending: he and his super PAC combined are shelling out $1.5 million this week, while Santorum's super PAC is spending $304,000 and he's personally spending nothing.
