The fine details of Trump and Russia are pretty much irrelevant at this point. Yeah, he's stupid and incompetent. Maybe he's trolling.
But he looks like a traitor, he acts like a traitor, and he's had ample time to come clean about anything shady in his past actions and instead he keeps lying and we keep finding more Russian connections. Dick Cheney liked to talk about how we had to act if there was a one-percent chance Al-Qaeda had a deliverable nuke or dirty bomb. Trump working against the interests of the United States and violating the law and his Oath of Office looks a whole lot more likely than that.
Everyone from the Cabinet on down needs to proceed forward with the presumption that Trump is a traitor to the United States and needs to be impeached. Anyone who declines to do so is themselves failing their oath and should be recalled and replaced.
Funny thing is that when you're churning out this kind of sanctimonious bullsh**t you probably believe what you're saying the moment you're saying it.
