Vice President Joe Biden wears a lot of different hats in the Obama administration. He's a longtime Senate insider who can negotiate with Republican Senate leader Mitch McConnell. He's a foreign policy veteran who helped to lead the transition in Iraq.

And one other thing to keep in mind, whenever there's idle political gossip about replacing Biden on the ticket with Hillary Cinton: He serves as a kind of White House ambassador to the middle class.

Rick Santorum waded into a controversial issue today when he gave an interview to El Vocero, one of the biggest newspapers in Puerto Rico.

The issue? The island's primary language.

The paper asked the former Pennsylvania senator if he would back Puerto Rican statehood if Spanish along with English remained its official languages.
