Got his ass kicked by a Millennial Communist asshole.
Not good.
It is good, actually.
On the practical side, it means that a D with seniority and status was thrown out and now there’s a low-ranking one in his place, thus weakening their position in the House.
On the ideological side, it means that the left is in a civil war. The violent ideologues vs. the greedy establishment vs. what few have some vestige of sanity—though many of those are already on the Trump train.
Of all of them, however, the greedy establishment is the most dangerous.
