The Demorats don’t have nearly enough votes to substantively alter the filibuster:
Five Senate Democrats have said they will not support a lowering of the 60-vote bar necessary to pass legislation.
Another four lawmakers say they are wary about such a change and would be hesitant to support it.
A 10th Democrat, Sen. Carl Levin (D-Mich.), said he would support changing the rule on filibusters of motions to begin debate on legislation, but not necessarily the 60-vote threshold needed to bring up a final vote on bills.
The Senate might be, at the moment, a liberal institution. But institutions are by their nature conservative.
