The "progressive" wing of the Democratic Party is on a roll, winning nominations and elections. Left-wing leaders are taking earned victory laps as they chalk up victories for candidates espousing socialism, hostility to Israel (and often Jews), identity politics, and other leftist positions that were until recently thankfully rare in American politics. But the radicals' support for Maine's deeply troubled Graham Platner, who won the party's nod to compete in the U.S. Senate race, shows the dangers posed by a movement that seemingly holds ideological lunacy as its highest value. It's not clear that anybody is in a position to stop them.
