Fun fact: there used to be a type of filibuster in the House too called the disappearing quorum. It was abolished in 1890 in order to pass a civil rights bill. However, the Senate didn’t follow the House’s lead and so we got another 75 years of Jim Crow.

I disagree that laws would change back & forth. They still have to get through both Houses of Congress and a presidential signature. Every election brings new issues to the fore while others recede. It’s not hard to imagine swing districts Republicans refusing to vote for a national abortion ban.
