Not always. He could have lost fair and square, but he didn't.Or you know the more simpler explanation. Trump set up a narrative that is always going to be correct and primed his followers to believe it.
I am not a Trump follower, I don't even like the guy that much, he didn't primed me to believe anything, I didn't even know what he said before the election, I think I have only listened to 2 of his speeches in my entire life, and yet I believe he was robbed.
You can believe whatever you want.
I'll do the same.
