There was no Quit Pro Quo with Trump because: 1) Ukraine funding had already been determined and could not be withheld. 2) a 20 year treaty with the U.S. and Ukraine states that the U.S. and Ukraine will assist each other in investigations. Also, the transcripts show no evidence of Trump threatening to withhold anything. Democrats and Adam Schiff made it all up out of thin air.
They ran Russian Collusion against Trump, even though he committed no crime.
Now they are running Ukrainegate, even though Trump committed no crime.
They are never going to remove Trump from office without courtroom level evidence of crimes.
Even though it is destined to fail, Pelosi thinks the Dems House majority is more likely to survive the 2020 elections if she appeases the Far Left radicals who have been demanding Trump's impeachment since the won the 2018 election.
There is no avoiding that the House is going to pass articles of impeachment, that was certain as soon as Dems took the majority, the only question has been what would be the pretext.
