The 112th Congress was faced with 400 filibusters. Apparently this was not enough to convince the 113th Congress that something needs to change. Only 48 Senators support a change in rules requiring Senators to stand in opposition to a bill.
Currently, Senators can just quietly state they are in opposition. In turn, 60 votes are required to overcome the filibuster.
According to the HuffingtonPost, “seven within the Democratic caucus who have yet to sign on are Sen. Carl Levin (D-Mich.), Sen. Mark Pryor (D-Ark.), Sen. Patrick Leahy (D-Vt.). Sen. Max Baucus (D-Mont.), Sen. Jack Reed (D-R.I.), Sen. Barbara Boxer (D-Calif.) and Sen. Dianne Feinstein (D-Calif.).”
Senator Carl Levin, along with John McCain (R-AZ), submitted a competing idea, which does not require Senators to stand. The idea is – well – just a smoke screen to block the option for filibuster reform.
