The Democrats’ left wing exploded, threatening to replace Mr. Schumer with someone like, say, Jerry Greenfield of Ben & Jerry’s. Mr. Schumer says Republicans will be blamed for the fallout (see any media coverage of government shutdowns). Rep. Alexandra Ocasio-Cortez, the fast-rising Bolshevik ingenue, has been mentioned as a possible replacement for Mr. Schumer, who faces re-election in 2028. Some Republican strategists are giddy over the possibility of campaigning against a Democratic Party that has Mr. Mamdani as its poster boy. Mr. Van Hollen wasn’t remotely concerned when President Barack Obama weaponized the IRS and intelligence agencies against conservatives and invented the treasonous Russian collusion hoax against President Donald Trump.
