Hmm: Bob Corker having some success selling debt-ceiling compromise to Dems

But as he’s barnstormed this conservative state over the spring break, he’s trying to cut to the chase, pitching an ambitious bill to create a mandatory cap on federal spending as part of a deal to raise the $14.3 trillion debt ceiling. It’s a message that’s catching on: More and more Republicans are calling for hard caps on spending and moderate Democrats — desperate for a palatable way to vote to increase the debt limit — are starting to buck White House officials who are lobbying Democratic senators to oppose Corker’s bill…

Like many Republicans, Corker realizes the vote to increase the debt ceiling will come under fire from the tea party wing – even if they win serious concessions from Democrats. And Corker is already receiving some political blowback for his effort to lure Democrats — some Republican officials worry he’s giving bipartisan cover to vulnerable incumbents, like Claire McCaskill of Missouri and Joe Manchin of West Virginia.

“Corker’s heart may be in the right place on this legislatively, but it would help if he was more focused on winning back a Senate Republican majority, than hurting the feelings of vulnerable Democrats who recognize the political cover this affords them,” said one senior GOP aide. “McCaskill, Manchin and others can vote for it, and campaign on it, knowing full well that Harry Reid and Chuck Schumer have enough votes to kill it.”
