Rick Santorum said Mitt Romney's tax plan is Obama-style class warfare because it raises taxes on the wealthiest Americans. "Mitt is a rich and out-of-touch elite from Massachusetts and can't identify with ordinary folks," Santorum said. "You can trust guys who have as much money as Mitt. I certainly couldn't afford to make a $10,000 bet like he tried to do because I make only about $17,000 a week."

Sarah Palin said she can't understand why Mitt Romney is getting the Tea Party vote in states such as Pennsylvania and Michigan. "Mitt campaigned for Tea Party candidates like Christine O'Donnell and Nikki Haley," she said, "so I can see why those individual candidates might endorse him, but why would the Tea Party endorse Mitt when Rick Santorum and Newt Gingrich are available? Those guys spent years in Washington and as part of the Republican establishment, they should be the guys getting the Tea Party endorsement."

The Koch brothers, who donate to the Tea Party, pump up gasoline prices by increasing the supply, says Obama reelection campaign manager Jim Messina, who learned economics in college by selling University of Montana tee shirts at a loss.
