It is important for the protection of the office of the President. If an impeachment takes placed based on no crime - then every future president from here on out can be impeached once the other side gains a majority in the house. It undermines the office of the president and should not be tolerated - even if it helps President Trump in the long run, it should never be allowed to happen.
The office of the Presidency lost all respectful demeanor with #42 and #44.
Rule by impeachment is fine with me. As long as Trump can continue to do what he is doing, I will be content to not worry what the Dems do.
