After yesterday’s part anti-establishment and part anti-boomer election results in NYC, you’d think Sen. Ed Markey, 78, might have waited a bit before unveiling a re-election endorsement from a fellow near-octogenarian, establishment, boomer pol, i.e., Sen. Elizabeth Warren, 76. But, nope, Markey probably sees the progressive wind at his back due to 33-year-old socialist Zohran Mamdani’s primary win yesterday in New York. … And establishment Dems sleep walk yet again toward another Original Sin-like moment. … It’s going to be interesting next year to see how Mass. progressives, who have lately been touting the need for younger party leaders, handle the Markey candidacy. My assumption is that, of course, they’ll conclude that objections to “overripe baby-boomers in or near their eighties who insist on hanging around” apply only to non-progressive incumbents.

Fyi: Obviously, Mamdani’s impressive win yesterday in NY wasn’t only about anti-establishment and anti-boomer sentiments. It was also about young voters pushing the party to the left and common-decency opposition to a sexual predator. See “Confession of a moderate NY Democrat” below. … Fyi, II: yet another overripe baby boomer who insists on hanging around is running again for the U.S. Senate in New Hampshire, as the Herald reports.
