I have reviewed a book explaining the case for impeaching President Trump. The author considers himself a centrist – extreme centrist is the term he uses. The case is explained well.
If you are a Republican, you should not excuse a behavior in a fellow Republican that you would condemn in a Democrat. And if you are a Democrat, you should not excuse a behavior in a fellow Democrat that you would condemn in a Republican. Unfortunately we have seen little of that in the past few months of Impeachment hearings.
Another perspective from a conservative point of view is offered in today’s NY Times. The Conservative Case for Impeachment — and Removal by Bret Stephens is well worth reading.
