Here's where I'm talking out of my hat.  I'll not even make the attempt at correction.
Both of my statements were meant as self-referential hyperbole; over-the-top rhetoric.  
The Olsteen-like preachers do draw fantastic numbers, on and off screen, and their "gospel" spreads like a plague.  I have a friend in Nigeria who is constantly amazed by the growth of the movement there.
For you second sentence, I'd have to look at numbers.  The contrary-like statement is "surely a huge number of denominations" doesn't equate to "equal distribution among them."
To your last I reply, "Bread and circuses" and agree that Trump outmaneuvered everyone in the "tell 'em what they want to hear" game.
