Why do we think Clooney would make a great President? Well, we've seen him play Presidents or politicians in movies more than once, and he's always very convincing in the parts. So much so, we think he'd probably be a natural fit. Politics is a lot like acting in many ways, as you're required to try to be all things to all people. Clooney has been doing that all his life, with the exception of his stint as 'Batman.' We never want to see that again, George. Sorry!
Clooney's acting career is, by his own admission, beginning to wind down. He once denied he'd ever been interested in running for President in 2011, but has seemed to soften that stance in recent years, admitting in 2017 that it 'sounded like fun.' Clooney is known to despise Donald Trump and all that he stands for, and so would probably run on the premise of being Trump's complete opposite.
