It’s officially open political vote season on the Senate floor, and Sen. Mark Pryor, D-Ark., is the latest vulnerable 2014 incumbent to benefit from Majority Leader Harry Reid’s power of the calendar, Meredith Shiner reports in Roll Call.  

The Senate voted Monday evening on legislation championed by Pryor — and co-sponsored by five Democrats who also are in-cycle — to repeal $6 billion in cost-of-living adjustments to military pensions agreed to in the 2013 bipartisan budget agreement. The legislation, which is not offset by spending cuts elsewhere, is unlikely to garner any Republican support in its current form, even though GOP senators moved to open debate Monday. Republicans likely would object to spending increases and to date have not offered Democrats alternatives they would accept. But Reid circumvented a committee markup to bring the bill straight to the floor so Democrats could record an up-or-down vote. The result? Just one of many votes Democratic leaders hope to hold in the months to come to benefit their most embattled members.
