Criticizing the Stalinist kangaroo court of the commissars was a good tactical beginning. They don’t have the votes to stop the actual impeachment vote but they can harass and bleed the Democrats until they get to the Senate. Once in the Senate Trump and his lawyers will have full reign to argue that Trump as the chief executive of every Federal agency including Justice had every right and obligation to examine how and who was using the Ukraine as a prosecutor free corruption zone. Not only will Hunter Biden be called but Paul Pelosi , Nancy’s son, also a man with no energy expertise became somehow enriched in the Ukraine. They will testify or take the 5th. Either way they face indictment and arrest. If Nancy goes through with impeachment, her son will have severe problems. So will other Democrats. It will be interesting to see if Nancy tries to walk it back.
All your points are valid and that simply means this will never get to a senate trial - you can bet your bank on that
Our great and wonderful president Donald J Trump has the best lawyers on the planet and you can bet that he knows the long game he knows every game and hes just letting the Democrats hang themselves right now
