Mitt Romney wins the 2012 presidential race if the campaign is about "issues" and not his business record or tax returns, former Sen. Rick Santorum (R-Pa.), a Romney surrogate, said.

"If the campaign is about issues, we win," Santorum, the former presidential candidate, said in an interview with The Daily Beast. "If it’s about Mitt Romney’s record as a businessman, then we don’t win. If it’s about Mitt Romney’s tax returns, then we don’t win. If it’s about whether people like Mitt Romney more than Barack Obama, then we don’t win."

Democrats have repeatedly hammered Romney on his refusal to release more than his 2010 and an estimate of his 2011 tax returns. Romney has responded by saying he is not hiding anything and he has released a sufficient amount of returns. Additionally, Democrats have tried to portray Romney's business record as head of venture-capital firm Bain Capital as one of making profits by drastically reorganizing companies, oftentimes by cutting jobs.

The Romney campaign, for its part, has responded that Democrats — the Obama campaign in particular — are simply trying to distract from discussing the country's faltering economic recovery.

Santorum repeated that criticism of the Obama campaign.

"Obama is not really out there defending his record," Santorum said. "He’s just attacking Romney and playing the class-warfare game."
