Impeachment will be expensive, time-consuming, will rile the MSM up like it hasn't been in years, and will have an unpredictable outcome in the big picture.
Even though Trump is not in danger of conviction by the Senate, no one can predict where events will lead in the course of a media circus:
Masses of people will do stuff; non-profits will be formed; legal actions will be filed.
Having impeachment as part of any "plan" would be asinine and very low IQ strategy.
