of course they will. Biden has already endorsed it.
ever since Obamacare Dems have no reason to fear the ballot box. nothing that is passed is ever repealed in this country and SCOTUS has self-neutered judicial review. Trump and Congress had 2 years to act on a whole host of issues but instead they yielded to the filibuster.
if you were a Rat why would you NOT pass everything on your wish list and then dare the GOP to repeal it?
The only reason the rats would nix the filibuster
is if they believe they will never again be in the minority.
And that should frighten us all.
