The filibuster's fate is already decided. Just look to the 2022 Dem Senate candidates.

Supporting filibuster reform is now a must-have position in a Democratic primary.

This is true in highly contested races in swing states, like the open-seat race in Pennsylvania and the possible challenge to incumbent Republican Sen. Ron Johnson in Wisconsin, if he chooses to run for reelection. It’s also the case in the more challenging environments of GOP-leaning states such as Kentucky, Missouri and Ohio.

“It’s a combination of some bolder people running for office and a recognition throughout most of the Democratic Party establishment and up-and-coming candidates that we’re in asymmetric warfare where the Republican agenda, from taxes and judges, can pass with 50 votes while the Democratic agenda needs 60 votes,” said Adam Green, co-founder of the Progressive Change Campaign Committee…

“The filibuster is not going to be here in five years either because Democrats will have expanded their majority with candidates like these or because Republicans take over and end the filibuster themselves,” said Eli Zupnick, spokesman for Fix Our Senate, the main filibuster reform coalition.
