Democrats are using Mitt Romney as leverage to push Senate Republicans to support legislation that would prevent student loan rates from doubling to 6.8 percent.

The top two Senate Democratic leaders called on Romney to enter the Senate debate after Republicans voted along party lines to block student loan legislation.

“Mitt Romney says he supports what we’re trying to do. I would suggest he pick up the phone and call Sen. [Mitch] McConnell [(R-Ky.)] and tell him he favors what we’re trying to do,” said Senate Majority Leader Harry Reid (D-Nev.).

Senate Democratic Whip Dick Durbin (Ill.) also called on Romney to take action.
