It takes 41 to vote down cloture but not 40 to filibuster. A filibuster needs just enough courage to keep someone at the lectern 24/7, to keep it from being put to vote. Senator Robert Byrd is legendary for his ramblings while stalling legislation he stood against. With C-SPAN, perhaps Senator Sessions, Senator DeMint and a few others could rotate and read the Declaration of Independence, U.S. Constitution and McGuffey’s Reader...and actually educate some people.
REMEMBER THE ALAMO.
BUMP
It doesn’t take 41 to vote down cloture. It takes 60 to INVOKE cloture.
Further, cloture is the way to end a filibuster. They already are under an agreement which controls the debate and doesn’t allow anybody to have the floor, and they’ve been careful to only give the floor to opponents under agreements that set time limits.
