"Senate Democrats could vote to abolish the legislative filibuster, and then pass Biden’s plan on a party-line basis."

"But West Virginia senator Joe Manchin has vowed to keep the filibuster in place. In effect, this means that all regular legislation will need 60 votes to clear the Senate. The only exception to this rule are bills passed through the budget-reconciliation process, which enables legislation pertaining to the federal budget to pass the upper chamber with a simple majority.... [I]t’s hard to see how Biden could really believe there are 10 GOP votes for a $15 minimum wage, or $350 billion in fiscal aid to states, or, frankly, most of the items in his proposal. It’s possible then that this gesture toward bipartisanship is intended to fail: Perhaps, the idea is to make the GOP an offer it can’t accept — but which the voting public overwhelmingly supports — and then say, 'Well, we tried for unity but those Republicans wouldn’t even support the $15 minimum wage that red state voters are clamoring for, so we’re just going to roll everything into one giant, partisan reconciliation bill.' Alternatively Biden may simply be making an opening offer full of provisions he’s ready to concede for the sake of a bipartisan compromise. Regardless, the proposal strikes a weird balance between maximalism and pragmatism.... Hopefully, Biden & Co. know what they’re doing."
