To say that something akin to a religion has risen around Trump wouldn't be a phrase too far off from the truth.
And like every religion, there must be hymns. It's happens with every major politician. I'm sure many can remember the small children singing about how Obama is going to lead us out of the dark times, or Hillary's weird country song.
