Reagan - divorced and remarried. Even started as a Democrat. Did a lot of good for the country and the world.
As for the Democrats, look at some of the worst of them:
-Woodrow Wilson - One wife at a time (married number two after first wife passed).
-Franklin Delano Roosevelt - one wife.
-Lyndon Johnson - one wife.
-John F. Kennedy - one wife.
-Jimmy Carter - one wife.
-Obama - one wife.
-Nancy Pelosi - one husband.
-Chuck Schumer - one wife.
-Bill 'DeBlasio' Wilhelm - one wife.
-Anthony Fauci - one wife.
FDR had mistresses.
You forgot Bill Clinton. He has had only one “wife”.
Big Mike ain't no "wife" ...
