I actually agree with her here, just not the way she hopes:
Trump not absolutely crushing the literal armed insurrection against the US up in Washington demonstrates the lack of leadership of which she speaks. If that had been squashed as soon as it should have been, it's quite possible we'd see less violent stupidity all over the country right now because it would be clear that violence in our streets won't be tolerated. Trump is just as hard on mobs and rioters as Obama was, and that's bluntly unacceptable.
From his statements since then, I hope Trump has learned his lesson but he's fooled me before. We'll see.
He's letting the children, and their helicopter parents who will never hold them accountable, discover just what the kind of world they want looks like.
