Do you really believe people care for the truth?
1. People don't understand what all that mumbo-jumbo means, but Trump is a successful businessman, huge one, if he says so, it will be true. Damned China!
2. The guy goes from one place to another in a 757 with his name plastered on it and there is a building in Manhattan with his name in giant letters. If he says he is self-funding, people will believe him, no check needed.
----
1. Trump voters don't like muslims.
2. Trump voter don't like illegal immigrants.
There, that's why the truth means nothing. You can't engage with Trump over this stuff, he will just grab you to the mud like he did with Rubio and you are finished.
You can't compete with decades of brand building, in the collective imaginary Trump is this successful billionaire that has buildings all around the world, and he is saying the stuff his voters want to hear (more or less secretly). No fact check, no humorist and no TV host is going to dispel that idea (sorry Oliver).
Honestly, stop underestimating Trump, or better, stop overestimating society.
