National Journal compiled a “whip list” below detailing the stated position of senators on a vote to significantly raise the debt limit without any cuts attached, or on a “clean” vote. The list is based on interviews, statements, other press reports and statements by Senate Republican leaders on the collective views of GOP conference members. Lawmakers’ descriptions of circumstances in which they would back an increase are noted. At least 50 senators, including several Democrats, have signaled they oppose a clean vote to raise the $14.3 billion statutory debt ceiling. That is enough to block it…

To allow passage of the measure, various groups of lawmakers are working on proposals to set future deficit reduction targets while leaving lawmakers to make specific cuts later. The proposals, intended for consideration alongside the debt increase, include varied automated mechanisms to enforce cuts if Congress does not act.

The most closely watched proposal may come from the bipartisan “Gang of Six” senators, who are expected to release a sweeping deficit reduction proposal based on recommendations last year by the heads of bipartisan fiscal commission. Two Senate Democratic aides said the gang’s proposal will come in pieces. One would set long term spending targets and would be designed for consideration first alongside the debt limit vote, the aides said. President Obama signaled general support for a plan that caps spending in a speech last month.
