I had a thought earlier, and it turns out several others have had the same thoughts.
So Bernie Sanders is not going to make it in 2020. I feel that's a given at this point. The man's going to be 79 in 2020 and 80 in 2021. Trump himself is getting up there, clocking in at 70 years old. He's actually the oldest person ever elected POTUS.
We're a bit weary of the '40s because they seem a bit too young to have enough experience. We're also a bit too weary of the '70s because they're bordering on senile and the upper end of the life expectancy. Somewhere between 55-65 is preferred. And lo and behold, there is someone coming out of the woodwork who is in (the lattermost end of) that range. He keeps saying that he's not running for president, but I think he'll change his mind. And you know what? I don't even care that he's a billionaire.
I don't care that Donald Trump is a billionaire at all— I care about the kind of billionaire he is. Of course the degenerate-minded will only hear that I am suspicious of his wealthy background and think I am a pinko, because they can't fathom more than one truth at a time.
Now that Trump has opened the floodgates, it feels like literally anybody can run for president. The idea of Kanye West being president is no longer beyond imagination. Same thing with Kim Kardashian. But if there's one person I could actually get behind, someone who's a leader in sci-tech and American...

"Hold on, Yuli— that's way too close. Gates should crush Trump ten times over!"
1) Cite your evidence. There's no telling how popular Trump will or will not be by November 2020. He could be Reagan circa '84, or he could be Hoover circa '32. I've been saying it's more than likely he's going to be the latter, but seriously, who knows?
2) I still just can't see anyone matching the sheer youth enthusiasm Sanders brought. Sanders had an actual history; if you weren't sure of his words, look at his actions. That's what I've been judging Clinton and Trump on, and is one reason why I laugh in the faces of Clintonoids and Trumpettes who keep trying to convince me their candidate/president is the best based on their words. A lot of Millennials liked Sanders because of his actions, his history, with his current words actually hitting home because he had the actions to back them up. Trump doesn't have that; a decade ago, he was a Democrat. Clinton sure as hell doesn't have anything like that; 5 years ago, she was against gay marriage and LGBT rights. Gates has a lot of action behind him, but a lot of it is suspicious. His charity group has done a lot of good, but some older types still remember how ruthless he was in the '90s. They may try to smear him with those actions. And it could work, because you know the saying— Leftists Fall In Love, Rightists Fall In Line. It doesn't take much to disillusion a leftie.
3) Gates is an atheist. Enough said. That alone could bring out record numbers of the evangelical vote.
It's tough to call whether or not Trump will be a success or a failure. I was sure that he would at least break the 50% popularity mark again by legalizing marijuana in 2019, but the recent statements by the White House suggest that's a fleeting dream. Which should've been expected considering who Jeff "I Thought The KKK Were Alright Until I Found Out They Smoke Weed" Sessions is. Trump isn't an autocrat; he has an administration, and his administration is packed to the brim with conservative authoritarians. Gates might prove to be more libertarian than most expect, considering he's a child of Silicon Valley. And by 2020, that may be a problem.
