Schumer's leftward drift ahead of his reelection campaign is a trend I've registered for a year or so now. It's a powerful vindication of the Bernie campaigns, of the many successful progressive local challenges in NY since 2018, and of Markey's win. https://www.nytimes.com/2021/02/07/us/politics/schumer-impeachment-new-york.html
I know it's fashionable in some quarters to sneer at the idea of "pulling the Democrats left," but it's actually working and we should keep doing what we've been doing.
The point here is emphatically not "Schumer is good now and we should be grateful." The point is that the incentives are shifting; this is bigger than what we think of individual politicians. Activist pressure (combined with seismic economic crises) produces results.
My replies: "No it doesn't, actually we suck, our efforts are worthless and they always will be, you idiot, you sap." Optimism of the will!
