Whatever you think of ex-president Trump…
Impeaching a defeated President a week before his term ended was an abuse of power. Add that to fact you knew you were never going to convict, it became a farce.
The people had spoken, Biden was to become President. Congress had/has work to do getting a new government in place. All this grandstanding for the cameras during the impeachment trial was a waste of time when the outcome was already known. It was divisive and so unnecessary. Good for rating, not so good for the Republic.
Finally the goal of the impeachment was to prevent the American people from voting for Trump again. The right of the people to vote for the candidate of their choice should not be up to Congress to decide. Congress was trying to disenfranchise the American Voter because they assumed they knew what was good for them.
