In the US, you can’t sell a product with a chance to receive a prize without having “no purchase necessary” and a means to enter for free. Mr. Beast did not do this in the past and also changed the terms for the lottery after sales.
Him being registered republican doesn’t necessarily mean he still feels that way. He made a blue political donation. Some people register with a certain party just because their parents are present when they sign up.
I don't think there is currently enough public information to build an accurate profile on him.
