Here’s another way to look at why Republicans swept the 2024 elections: It’s the fault, only partly, of course, of the gerontocracy of the Democratic Party. Going back through history, it’s hard to find a time when a party’s leadership was so far along in years. The founder presidents retired in their mid-60s. Andrew Jackson retired at 69, Abraham Lincoln was murdered at 56, and Ulysses S. Grant retired at 54. Theodore Roosevelt died at age 60, Franklin Roosevelt at 63.

Quite a contrast with President Biden, who was older when he was inaugurated than President Reagan was on his last Air Force One flight home to California. Mr. Biden, who was born in 1942, was installed as the Democratic nominee in 2020 by the House majority whip, James Clyburn (1940), and was pushed out of the 2024 nomination by the still very active Speaker Pelosi (1940).
