I haven't delved into this much, so forgive me if I'm off-base. If he has a backer, they've been with him for a long time, like decades. Trump's tenacity has been consistent throughout his career. He's faced so much adversity and still prevails. So his backer either gives him that confidence, or has been utilizing it.

We would be talking about someone that is simultaneously "superior" to Trump (in so far that Trump would take orders from them) and loves this country possibly more than Trump, which is seemingly rare. They don't have to be wealthier than Trump for these to be true, but they probably are. They're so under the radar that Trump has likely not been seen with them over the past four years.

The time traveler theory is pretty far out there, but that's an easy way to explain all of this. There is also divine intervention. I don't think we'll ever know for sure unless they come out. But I pray that we ultimately benefit from their relationship more than we already have. I hope the work they've done together truly is the saving grace of this country, and the world at large.
