Technically, impeachment is a political process, not criminal, so the ruling doesn’t apply. But of course impeachment is for “high crimes” and since it can’t be a crime anymore, impeachment also can’t be used. Or so they will argue when Trump drops a nuclear weapon on Santa Monica.
It's so patently absurd and fundamentally *non-judicial* on its face; the whole ruling reads like a Lewis Carroll THROUGH THE LOOKING GLASS passage at absurdity that only has the pomp of high-minded language. Just insane.
"We're all mad here," now.
