A lot of aspects of American life likely could change sometime this afternoon.

At 11 a.m. (CST), Donald John Trump will become the 45th president of the United States. Barack Hussein Obama will exit the world stage and jet off to Palm Springs, Calif., for some well-deserved R&R with his family.

The new president will attend a parade, shake some hands, then venture into the Oval Office.

Then — he says — he will sign some executive orders, which he is entitled to do.

Will these orders undo some of the many positive aspects of Barack Obama’s presidency? Trump, after all, has called the current president a “disaster.” He’s said his policies are “stupid.”

Trump, who calls himself a “smart person” with a “good mind,” and someone who will surround himself with the “best minds” and a team that has highest collective IQ of any in the history in the history of the republic, will get to work to make his mark on the presidency.

What that entails, at this moment — on Inauguration Morning — remains virtually anyone’s guess.

I am going to hold out hope for one thing to occur. It will be that the sun will set tonight and we’ll all be able to awake Saturday to yet another beautiful sunrise.

I am going to pray that the new president is successful in whatever plans he has laid out for the next four years. The consequences of failure are too grim to ponder.
