Sen. Chuck Schumer (D-NY) has never faced a revolt like this before.

The broad left has never pulled its punches when it comes to the eight-term senator, suspicious of his Wall Street ties and unhappy with willingness to strike deals with Donald Trump. But it’s not the Left that Schumer has to worry about these days. Over the past week, Schumer has faced an unprecedented barrage of often public criticism and rebuke from within his own party, longtime Democratic loyalists, and party-aligned media outlets.

The point of controversy was Schumer’s decision to cave on the congressional standoff over an impending government shutdown. While many Democrats, even those in tough districts, favored using the risk of a chaotic shutdown as leverage to extract concessions from Trump and Republicans — reversing some of his most damaging cuts, for instance, or carving out protections for Medicaid and Social Security — Schumer argued a shutdown would be too disruptive and harmful, potentially giving Trump’s administration new opportunities to extract even more government cuts, and lent the crucial Democratic support needed to get the spending bill over the line.
