Senate Democrats, led by Senate Majority Leader Harry Reid (D-NV), are looking to neuter the filibuster, the procedure often used by the Senate minority party to stall or nix bills.
Reid's move is infuriating the GOP, and could jeopardize the post-election mood of bipartisanship.
Reid is considering rules which would ban filibusters from preventing the start of debates and force senators to be both present and talking during a filibuster, according to Politico.
This doesn't sit well with Senate GOP members, who say that eliminating the filibuster would undermine the Senate's consensus-building purpose, and cause the chamber to run more like the majority-vote House.
Reid himself opposed similar changes to the filibuster in 2006 when he was a part of the minority party. Now, however, Reid claims that Senate Republicans abuse the filibuster so often, that it's become nearly impossible to get routine tasks done. The Majority Leader has threatened to use what he once called the 'nuclear option' - which allows for a 51 majority vote, rather than the normal 67, to change Senate rules.
