Following his decision to vote for a Trump-backed government funding deal that keeps the lights on through September, Senator Schumer has faced fierce backlash from his party’s liberal base — so much so that he now has to cancel a leg of his book tour due to “security concerns.” If he were to be pushed out in the coming months or years, the question is: who would most likely replace him?

The gerontocracy has been on plenty of voters’ minds in the last few years, especially considering the seismic impact President Biden’s obvious deterioration had on the 2024 results. Mr. Schumer, at the age of 74, is technically the highest-ranking Democrat in America as the Senate minority leader. He’s the only person in Washington who could realistically pump the brakes on aspects of President Trump’s agenda by using the filibuster, which is something he declined to do just last week, drawing the ire of some of his colleagues.
