Rep. Paul Ryan's (R-WI) "roadmap" budget plan -- which calls for balancing the budget in 50 years by effectively privatizing Social Security and Medicare -- could become an excellent political tool for the Democrats, says former Clinton adviser Paul Begala.

Begala, in an interview today with TPM, said Democrats should force the GOP to bring their ideas into the public eye.

"Why don't we put Mr. Ryan's budget up to a vote?" he said. "Make them vote on it."

Democrats, he argued, should stop calling Republicans the "party of no."

"They have ideas, and lots of them. And their ideas ruin the country," Begala said.

What the Democrats have to do, he said, is make the 2010 elections a choice between Democratic and Republican ideas, instead of a referendum on just the Dems. (A point Chuck Todd made earlier this week.) The way to do it, he said, is to highlight those GOP ideas.

Begala said the White House has already begun to do this, with both President Obama and Office of Management and Budget Director Peter Orszag mentioning Ryan's budget.

And Congressional Dems have seized on the opportunity to call out the provisions that would privatize Social Security. Reps. Chris Larson and Linda Sanchez have introduced a resolution opposing such privatization, which would force Republican lawmakers to vote on the idea.
