WaPo's Henderson: 'Don't Believe Liberal Media' signs at Santorum events

Nia-Malika Henderson, "And that's what happens when you are running for president. This is the vetting process that every candidate goes through. I think one of the things that Santorum is doing too, he is playing to the base. This is red meat for the bait. You see people holding up signs saying "Don't Believe the Liberal Media" but he's able to get excitement on the base and that's an edge he has and Romney doesn't."
