Senate Democrats appear unlikely to nuke the legislative filibuster, despite intense pressure from the left in the wake of this month's two victories in Georgia. Starting Wednesday, Democrats will control a unified government for the first time since 2010. But the slim 50-50 margin in the Senate is threatening to box in progressive hopes of going big with sweeping policies unless they can convince senators to nix the 60-vote hurdle that would require GOP support for most legislation. Supporters of going “nuclear” would need the support of every member of the Senate Democratic caucus to get rid of the filibuster, but several aren’t on board.
