I think we can guess a few things - I think Hillary won in 2016-α against Jeb, who was weakened in our timeline by the changes made to the Republican primaries after 2012 (which were influenced by Trump through Reince Priebus, another possible time traveler, judging solely by his name), as well as early targeted attacks from Trump himself. But Trump had a strong strategy in mind for beating Hillary, which he was absurdly confident in as far back as 2012 - and I think it’s possibly because he saw it work already. I think he might have copied his style, key elements of the campaign (the MAGA hats? the critical Rust Belt working class focus? his Twitter media manipulation? maybe the hacking of the Hillary campaign was accomplished using Trump’s foreknowledge?) from someone else who ran against Hillary in 2020-α, who was possibly even more of a strident nationalist than Trump and was riding an even greater populist backlash against Washington DC.

Perhaps this was one of the things Trump came back to prevent - something that became much more worthy of being called a fascist takeover of the US. And he did it using their methods because he knew they worked. Maybe the hats originally just said ‘Make America Great’ and Trump added ‘Again’ because for him, it’s the second time.

I’m not sure who this mysterious nationalist candidate could have been, but maybe Andrew Breitbart survived in the original timeline (did a time-traveling Trump orchestrate his mysterious death?). Maybe it was actually Richard Spencer? Maybe it was a reality TV host, which would explain why he did The Apprentice. Or possibly Steve Bannon - that would explain Bannon’s position in the Trump administration, perhaps.

Trump being a time traveler might explain his odd organizational structure, too - the handful of insiders who run everything and report directly to him could be the only people who know he’s from the future and can understand what he’s actually trying to do. And all the people who are otherwise unknown/from humble backgrounds but have been given a large degree of authority - it could be that Trump knew them in the future of the alpha timeline. I think one could argue that the way Trump does things is exactly how one would expect a time traveler to run an organization. Especially if that organization is inexplicably effective for how small and ad-hoc it seems - like if it can run a successful presidential campaign and manage billions in assets with just a few not-that-competent-or-qualified-seeming people.

If we assume that Trump’s major policy initiatives are anticipating the problems he’s seen the US run into in the alpha timeline, it doesn’t paint a pretty picture. I think his seeking detente with Russia and attempt to weaken Chinese industrial power and enhance America’s domestic industrial base suggests that in the alpha timeline, the US faced a strong Russo-Chinese alliance in some manner of conventional conflict - perhaps a new cold war, with many proxy conflicts around the world? Maybe a direct conflict in the South China Sea?

His rhetoric around Israel is basically ‘I’m going to be amazing for Israel’ with few explicit stated benefits - maybe in the alpha timeline, Israel suffered a great deal and possibly was destroyed, but Trump is confident he can prevent that? Maybe that has something to do with his similarly sketchy but apparently powerful hatred for Obama’s Iran deal? And the Wall - what did Trump see happen to Mexico that he’s so keen on building it so quickly? A natural disaster, a plague?

Perhaps also there was a terrorist attack early in 2017-α and Trump’s seemingly hamfisted immigration order was designed to disrupt it in our timeline - there’s a lot about the order that doesn’t add up unless there’s something bizarre like that going on. And tonight he made it obvious that he already knew the outcome of the Super Bowl, of course. Anyway, I think as his administration goes on, we’ll see more signs of the future Trump came back to prevent. Keep watching!
