The Obamas will get the last laugh. They're 56 and follow healthy lifestyles. Trump is 74, thinks riding in a golf cart is exercise, and eats cheeseburgers in bed.
The truth has been seeping out despite Trump's best efforts to put his fingers in the dike. In fifteen years time, he will be dead. Any airports and roads named after him will revert back to their previous names (after all, part of I70 was renamed Mark McGwire Highway till they found out about the steroids...) The history books will have crowned him worst president in history, as future students read about him and wonder how their grandparents could have been so misled. The name "Trump" will have become synonymous with evil and corruption.
President and Mrs. Obama will direct a philanthropic foundation that helps people around the world and in our own country---and it will never get shut down for misuse of funds as Trump's was. The Obama girls will make a positive difference in the world.
They have much to look forward to when Trump is no longer president---and lucky them--they will live to see their vindication.
