I have been a fan for introducing term limits for US congress, the main reason being that I think the risk of corruption goes up exponentially the longer they are in that position. I also see no reason why the people cannot chose who they want so long as elections are honest. I'm not sure how to resolve that conflict. (In this particular case though, I think President Trump is a very rare person, that I don't think would ever become corrupt because he is not bribable)
