You’re really trying to strawman me and aren’t making good faith arguments here so I’m not going to waste too much time on a response… but take 51 and then subtract 2 from it (for Manchin and Sinema who won’t vote with dems on these issues) - is that 50? Besides that dems also don’t control the house.

We don’t have to guess, they tried. 50 is enough if you can get 50…on these issues the dems couldn’t get 50 even when they had the house. Guess which two senators opposed filibuster reform? Guess which two senators also very publicly stated they wouldn’t vote for packing the supreme court?
