Manchin has claimed since the beginning of the year that he wouldn’t support eliminating the filibuster and even shouted at one reporter who asked him if there were any potential circumstances under which he would alter his position: “Never! Jesus Christ, what don’t you understand about ‘never’?” Lately, however, his position has indeed been “evolving.” Recently, for example, he reiterated his resolve to protect the filibuster on NBC’s Meet the Press, but he added a new caveat on Fox News the same day: “Maybe it has to be more painful, maybe you have to stand there. There’s things we can talk about.” Manchin appeared to be suggesting a return to the hoary “talking filibuster.”
Until the 1960s, if a senator who wished to use the filibuster to stop a vote on a particular bill, he was required to stand and speak without yielding the floor. A group of senators willing to tag-team could extend the filibuster for weeks by rotating speakers. The longest filibuster on record involved a cadre of Democratic senators opposed to the 1964 Civil Rights Act. Because the filibuster halted all other Senate business, these Democrats brought the Senate to a standstill for 60 days. Senate rules have since changed so a bill can be “filibustered” without shutting down the upper chamber. A particularly pernicious piece of legislation can be killed if it lacks the 60 votes required to overcome a filibuster.
As it happens, just such a bill has been introduced in the Senate. On January 19, Senate Majority Leader Chuck Schumer (D-N.Y.) announced that the first Democratic bill in the new Congress will be the “For the People Act.” S 1 is virtually identical to HR 1, which passed in the House on March 3. For the Democratic leadership of both houses, this is the Holy Grail, and they fully intend to ram it down America’s throat even if they must kill the filibuster. This is why Joe Manchin is getting so much attention: he and Sen. Kyrsten Sinema (D-Ariz.) are the only Senate Democrats who claim to support the filibuster.
