I disagree. GW was at least the governor of Texas before he ran for president. He had plenty of political experience, certainly more than the clown we have in office now. I don't know what is more distressing, the fact that Kanye, if it wasn't just the drugs talking, actually believes he can be President, or the fact that there are people who are actually serious when they say they would vote for him.
That is a fair point Trump is a businessman ran an Empire and became one of the wealthiest people around if anything he has respect for it, as corporate can also transfer in skills to governance.
Kayne would have a music empire behind him but no governance experience.
I guess that would leave Schwarzenegger or Arnold to fill in the gap for 2020 governor of one of the largest economies in the world (California), worked as an actor and is a ex-politician/celebrity up for the running.
