'Southern White House'. Ha, he's channeling Richard Nixon again. Nixon called his home in San Clemente CA the 'Western White House'.
Again, I don't have a problem with a president having a second home, per se. A number of presidents had them, including JFK and Lincoln, and most of them 'retired' to those homes after their terms ended. But these were private residences. Mar a Lago isn't a 'second home' in the traditional sense, it's primarily a Trump business enterprise, not a home, and he's using the Office of the Presidency to increase profits at that business. Sad!
