Here’s what Senate Majority Leader Harry Reid is considering: banning filibusters used to prevent debate from even starting and House-Senate conference committees from ever meeting. He also may make filibusters become actual filibusters — to force senators to carry out the nonstop, talkathon sessions.

Republicans are threatening even greater retaliation if Reid uses a move rarely used by Senate majorities: changing the chamber’s precedent by 51 votes, rather than the usual 67 votes it takes to overhaul the rules.

“I think the backlash will be severe,” Sen. Tom Coburn (R-Okla.), the conservative firebrand, said sternly. “If you take away minority rights, which is what you’re doing because you’re an ineffective leader, you’ll destroy the place. And if you destroy the place, we’ll do what we have to do to fight back.”

“It will shut down the Senate,” the incoming Senate GOP whip, Texas Sen. John Cornyn, told POLITICO. “It’s such an abuse of power.”

The push will happen at the start of the new Congress, when Reid will unveil a rules package certain to have some changes to the filibuster.
