For the latest edition of “Dialogue,” Philip Klein sat down with Rick Santorum, the former U.S. Senator from Pennsylvania and former GOP presidential candidate, to discuss his new book, Blue Collar Conservatives.

“We focus on growth, growth, growth,” Santorum said in a critique of the Republican Party. “I’m pro-growth. I’m for lower taxes. But the message is ringing hollow. It’s the same message that we’ve been using for 40 years, and the policies that we talk about to stimulate growth are the same things we’ve been saying for 40 years and there are a whole swath of people out there who aren’t succeeding, and we have to have a message that includes them.”
