So here’s a “what if” scenario. Trump’s folks discover the smoking gun that has the bulk of the Nation saying, ‘My gosh, the King doesn’t have any clothes on.” So now Trump needs to think about who the alternative Rat would be and how he’d play against them.
Perhaps, Trump is actually working for that alternative 'Rat.
And his threat to run as an Independent if he doen't gain the Republican nomination is designed to insure the alternative 'Rat's election.
