He has actual experience with a government lawmaking body which is more than Trump had. I don't know enough about his legislative life to judge it one way or another as I haven't been focused on him and it is too early to start the research. I'll do that when we get closer to the primary if he is one of the contenders.
I don't know or care if he earned his money legally. It isn't like he has billions gotten crookedly by not paying contractors and setting up illegal Universities. But if he did I sure as heck would not vote for him. That is a fact!
