In fact, much of the rules debate focused on how it would impact a potential Ted Cruz 2020 win,
so this report is believable.
What's difficult to understand is why Cruz was invited to speak tonight in the first place? If he doesn't endorse Donald Trump the optics are awful. And how enthusiastic will it be if he does.
He's largely expected to try to pull a “Reagan '76,” where the future president laid his own groundwork for 1980. But Ronald Reagan did endorse Gerald Ford. And how many primary challengers will a run against incumbent Hillary Clinton draw? I suppose it depends on how horribly she has messed up the country by then, as usual.
