He has no intention of being president. By “running,” he gets fame, name recognition, and money. Plus tv interviews, and book deals, etc, etc. Plus maybe a few airhead bimbos who put out for him.
He is even a less serious “candidate” than butter-butt.
No joke. He’s probably sick of being a crony-politician working for his relatives and wants a reality-show or be a host like Bill Maher.
