1. Trump has to run. It's his best chance at beating the current cases against him.
2. I bet Fat Ron won't run if Trump does. He is way to cucked to uncuck enough in time to no longer look like Fat Ron Trump Cuck.
3. With the Saudis, Russians, North Koreans, etc positioning how they are globally right now, there is way too many opportunities via chaos out there, for a guy like Trump, to not run.
