Burning tRUMP.

They are pissed

that Russia has been mentioned very very few times. Turkey, Syria, Saudis mentioned hardly at all. Emoluments...very little.

they aren't going after the pattern of misconduct, really just Ukraine and really just Biden even when it would be easy to make a case that the Russia angle and Trump's policies favoring Russia STINK TO HIGH HEAVEN. The Russia angle is actually much more important that the Biden angle wrt national security. After Russia, Ukraine, Turkey, China...how can we know that any foreign or domestic policy action the WH takes isn't corrupted? WE CAN'T KNOW THAT NOW! Yet...this angle is not mentioned today. I follow why this is not part of the current impeachment officially, but that shouldn't mean that Russia can't be mentioned. In many ways, Russia is at the heart of all this, and is much much worse than Ukraine by orders of magnitude.

So why are they ignoring the ongoing counter intelligence investigations, the many Russia-related convictions, the actions favoring Russia? Trumps obvious lies about having no Russian interests?

I'm hoping because there are still Russian loose ends being tied up and they don't want to jump the gun before ready. I'm also hoping the loose ends are tied into a beautiful impeachment and criminal knot before the senate votes.

Russia is the subject of another impeachment inquest. After we see just how many rubles have been shoveled into his tiny hands by various Russian oligarchs. Wait for SCOTUS on that one.

even a Republican can understand.

They're scared and jealous of the man. He's likable and knows how to articulate a good case in front of the court of public opinion.
