I agree. Do not think they will ultimately have the vote to impeach:
1. May not have votes. Nothing was proved. There are a number of Democrats in Trump districts (30?) who have to think long and hard.
2. Trumps pushing for a Senate Trial and the GOP talking about who they will call (which could be extremely damaging to the Democrats) should make Pelosi and Shiff think twice. Having him on the stand in the Senate could be very entertaining.
3. Obviously, will not get 20 GOPs in the Senate to convict; so just a PR stunt which will greatly benefit the GOP.
Only risk is if Chief Justice Roberts gets all super cautious and limits witnesses, testimony, etc. He did call Obamacare a tax! The legacy of the Supreme Court is more important to him than anything. You can bet he is a never trumpet as well.
