Gingrich is an enigma to me. He is well educated and smart, well versed on the Constitution, separation of powers, etc; yet he seems to have no aversion to chaos in politics and lacks, so far as I can tell, human empathy. But what is entirely missing from Newt Gingrich is integrity. The article you posted where Gingrich, without shame, pimps for a job in the Trump administration, is one of the most amazing distortions of truth I have ever read.
Gingrich is regarded as the father of acrimony in our present day Congress, the originator, in modern times, of the idea that democrats and republicans should not get along, and if they did, there was something amiss. He is the progenitor of government shutdowns and consequent inefficiencies, brinksmanship and coercion. He is the organizer of gangs of politicians bent on destruction of institutions for personal gain. Between Mitch McConnell and Newt Gingrich, I don't know which is the teacher and which the pupil. Both are terribly bad for the country.
