"Call his bluff". Obama threatens to veto XP Pipeline bill

Congress is packaging approval of the Canadian XP pipeline in with approval of extended payroll tax cuts. President Obama wants those cuts but threatens to veto the bill. 

Professor Reynolds of Instapundit says: "Call his bluff!"

“We are working on a bill to stop a tax hike, protect Social Security, reform unemployment insurance and create jobs,” [Boehner spokesman Brendan] Buck said. “If President Obama threatens to veto it over a provision that creates American jobs, that’s a fight we’re ready to have.”

The Democrats’ opportunistic drive to cut FICA taxes is most likely a death knell for Social Security, as many liberal commentators have noted.
