@snood,
I don't think he stomped over the rule of law because he panicky, I think he thinks he could and should get away with it. He is panicky because the story is not going the way he probably envisioned it going. His message of Biden is corrupt is not the main subject of the media the way he wanted it to be. This was a risky move, they thought they could get away with it if they avoided linking directly in the same sentence sequence, investigate Biden and aid money for security. They could sell it as investigate corruption of which the Bidens' were a major part of. Too much has come out, the text messages between the envoys are a gold mine IMO. Trump's own reconstructed phone call backs up a intelligent reading of a quid pro quo. The whistleblowers account has been backed up.
Now Nancy Pelosi has to hold an up or down vote for official impeachment articles to get underway. They have the votes. That way they can get the documents they need by law. Otherwise, the Trump administration will stonewall them.
Been watching and reading this since it started; almost obsessively. I watch with the sound off, can't stand it otherwise, even with hearing aides, its just so much noise. Much better to read it on caption. But the internet is best place to get most of the news. Just saying.
