Republicans have redefined morality, creating a version of the term many of their elders wouldn’t recognize.

The Grand Old Party that once campaigned for public office on a “character matters” platform and once went after a Democratic president hammer and tong because he messed around with women other than his wife now stands foursquare behind a president that has done far, far worse.

And no one seems to care.

Donald Trump has been called a man who builds his relationships on a “transactional” basis, in that he always is looking for something in return for his “friendship.” Let’s say his followers believe in a “transactional morality,” meaning that it doesn’t matter that the man is a slug as long as he adheres to public policy to their liking.

We have elected twice an individual who has denigrated a legitimate Vietnam War hero, mocked a handicapped New York Times reporter, admitted to serial philandering on all of his wives, acknowledged he has sexually assaulted women by grabbing them by their private areas, admitted he never has sought God’s forgiveness, been impeached twice for high crimes and misdemeanors, convicted by a jury on 34 felony counts, been found liable for the rape of a woman … and on and on it goes.

What’s the problem, the MAGA cultists ask. He selects judges who will toss aside a woman’s right to control her body, he does nothing to stem gun violence and vows to be “your retribution.”

Yes, we have entered a new era of morality in which we no longer judge a candidate on his behavior but only on whether he is a good fit politically.

This is a sad time for our still-great country.
