One reason Speaker Pelosi and other Dem House leaders wanted to avoid impeachment was that they didn't want the House to be defined by Trump and by the meaningless efforts to attack him. Instead, they've been unable to escape the gravity well of their own radicals and Trump.
As House Democrats were forced to kill a ridiculous impeachment proposal, and vote on condemning Trump's tweets, they were being defined by Trump and by opposition to him.
And that's a trap.
House Dems have a limited ability to do anything about Trump. Focusing on Trump alienates moderates and Democrats who want something meaningful. And ultimately alienates radical lefties with no sense of the practical limitations on their power.
And yet they're stuck in that trap.
