Fortune favors the bold. Conversely, most high-risk bets don’t pay off.

Rep. Seth Moulton (D-MA) will meet one of those contrasting political fates if, as expected, he launches a 2026 primary challenge against Sen. Ed Markey (D-MA). A Moulton Senate Democratic primary bid in Massachusetts, tantamount to victory in the deep blue state, would come amid growing voter concern about a growing political gerontocracy. Moulton, 46, is more than a generation younger than Markey, 79, who first joined Congress at the end of Gerald Ford’s presidency.
