Power Line’s Paul Mirengoff, who keeps closer tabs on which senators support what legislation than I, writes a rather upbeat analysis of why he believes Joe Biden (and his handlers) are unlikely to get a truly radical agenda through the Senate in the 2021-22 biennium.
His analysis mostly relies on a few named Democrat senators resisting demands to deep-six the filibuster. As others have noted, without the filibuster we would experience radical swings in national policy each time a new party held an (often narrow) majority in the Senate.
Will these senators hold out as Mirengoff predicts? Time will tell.
