Markey, looking to clinch another Senate term, leads younger rival Seth Moulton in blue state’s primary poll

Democrats have spent the summer ousting long-serving incumbents in primaries across the country. On Tuesday, Massachusetts voters will decide whether that generational revolt extends to the 80-year-old Ed Markey, whose younger Democratic rival has argued that the incumbent is simply too old to serve another term.

But the Senate primary in this heavily Democratic state flips a central dynamic of previous contests, where youthful progressive insurgents have targeted – and in several cases, toppled – older incumbents they derided as avatars of an outmoded cautious establishment.
