Fair question, and, what looks like an honest attempt at a conversation. Almost surprising...

So my opinion on this is that politicians don't need experience in politics to do the job. They need experience in leadership, since decision making, temperament, and personnel management skills will determine their competence. To me, a career politician is someone who might never had to develop any of those skills, just learned the game of power. But they might not even be good at it. Most of the politicians got to where they were at because of their connections or their usefulness to the true rulers. Meanwhile, the knowledge that a politician needs can either be learned in the first week, or acquired from competent advisors.

I don't believe Trump is a great example of someone who DOES have the skills to be a politician. If he was, he would have maintained the same support he had from Hollywood and the media right before he decided to switch to a republican and run for president. The black community and liberals that all loved him wouldn't have abandoned him and started the most massive smear campaign in US history. That fact that he can't explain his position for shit doesn't help either. I agree with nearly all of his political moves, but he completely fails at drawing the appropriate support for them. That's a shitty leader.

Regarding Biden, I don't know enough about his decision making skills, but he fails the temperament test. He likely fails at personnel management considering his lack of experience (did he lead anyone as VP? I could be wrong here) and that he didn't do a great job with leading a family if his kid is a deadbeat dad, junkie and obvious criminal. I haven't seen a single thing from him that impresses me, and his political ideology is endless totalitarianism, so he will never get my support.

Not going to act like any of the libertarians I vote for would have been amazing leaders, but at least they operating under sound ideologies that would make this country a better place. Which is probably what everyone else thinks when they go vote for their "lesser of two evils" presidential pick.
