Rand's pledge to filibuster still stands. But he won't get a chance if enough Senators sell us out.
Cloture - The only procedure by which the Senate can vote to place a time limit on consideration of a bill or other matter, and thereby overcome a filibuster. Under the cloture rule (Rule XXII), the Senate may limit consideration of a pending matter to 30 additional hours, but only by vote of three-fifths of the full Senate, normally 60 votes.
As of right now, one dozen Senators have pledged to join Senator Paul’s filibuster. We need to pressure 28 other Senators to effectively stave off Senate Majority Leader Reid’s scheme by either getting them to pledge to 'Stand With Rand' on the Filibuster or at least agreeing they will oppose any Cloture motion that would prevent a potential filibuster.
