Would Santorum Lose Popular Vote, But Win the Electoral College?

Nate Silver has an interesting article at the NYT (“Here Comes Class Warfare”) where he argues that while Romney would do better than Santorum in the popular vote against Obama, Santorum might lose the popular vote, but win the electoral college.  Silver focuses on Santorum carrying Ohio, Michigan and maybe Pennsylvania.

In making these calculations, I think Silver puts too much emphasis on class (he’s focused on working-class whites and Obama’s past struggles with them) and not enough on gender.

I think Santorum would turn off women at all income levels so much that he couldn’t possibly win.
