Massachusetts primary tests age factor as 80-year-old Markey faces younger rival

Massachusetts Democrats vote Tuesday in a Senate primary where 80-year-old incumbent Ed Markey faces a generational challenge from Seth Moulton, who argues Markey is too old. The race inverts the usual dynamic of progressive insurgents targeting incumbents, as Moulton positions himself as the younger alternative. Outcome will signal whether the anti-incumbent, age-focused wave seen in other primaries reaches Massachusetts.
