What’s wrong with his answer? Wolf was looking for a “gotcha” and Santorum basically responded by repeating back to Blitzer the same phrase that Rush says every day on his show: “Demonstrating absurdity by being absurd”.
The point is, he didn’t defend Rush, who has really been nice to him on air, or point out the media hypocrisy, like Mark Levin did tonight. I guess Rick was just being a team player, Team Santorum.
