I'm very excited to see @jbouie bring attention to the important expansion of the House Rules Committee in 1961, but it also suggests that Senate Dems can't easily or quickly undo the filibuster. 1/x https://www.nytimes.com/2021/01/26/opinion/democrats-schumer-mcconnell-filibuster.html
Rayburn did expand Rules to help a new Dem president (evidence that Speakers care about the presidential party!). But it also took 2 yrs of House libs pushing Rayburn to embrace reform. Dropping the filibuster may take a similar push by a coalition of Senate Dems. 2/x
The committee expansion was temporary, which made it more palpable. I doubt Schumer can credibly promise to suspend the filibuster for just two years. 3/x
Rayburn worked overtime to get a majority to expand Rules -- delaying the vote, lobbying lawmakers, etc. I suspect Schumer would have to work at least as hard, if not harder, to build a coalition to undo the filibuster. 4/x
