I can't discount Scarborough's prediction, either.
Demography is destiny.
And the democrat-communists have been intent on changing -- let me go so far as say "replacing" -- the "old" demographics of the country since the 1965 immigration "reform" act. Right now, they're succeeding.
And the replacements ARE NOT going to naturally lean towards the Republican side of things. Quite the contrary, we are importing them from parts of the world where the notion of limited self-government is nonexistent. And that, too, is "a part of the plan".
Mr. Trump won because he WAS NOT a "traditional" Republican. He was a one-of-a-kind candidate who jumped aboard a Republican horse, stole it and rode it to the presidency by associating himself with "the Republican brand".
No other Republican candidate could have won in 2016. Mr. Trump looks like he'll win again in 2020, but I predict that it will again be a "hard won" victory, not a landslide by any means. (I would happily eat those words on November 4th)
Right now, I see no one who can pick up the baton from Mr. Trump and run with it in 2024. Mike Pence? He would be like G.W.H. Bush following Reagan -- an inconsequential one-termer who would lose to the demo-commies in 2028.
If we don't "get the demographics under control" pretty quickly, none of this will matter. We're gonna be overwhelmed.
