I think you've got it wrong there. In almost any other election I'd be for Cruz. I suspect, though could be wrong, that most Trump supporters are similar. I'm not going to accuse you of it, but I think a significantly higher percentage of those who support Cruz are more likely to insult the other side and/or see it as an either Cruz or Trump thing.
That is to say, in everything I've been reading, the Cruz supporters are more often 2-dimensional.
You say: "it stuns me that these Trump supporters can only think in two dimensions."
So I say: "When a plane looks at something three dimensional, it can only see two dimensions."
Do you understand that statement? It's not the pot calling the kettle black ... it's one step further ... it's the pot calling the kettle a pot.
I assure you I am a kettle - in all three dimensions. You on the other hand, should check the mirror.
I do not see Trump as having the depth of conviction Cruz has, but I certainly understand the desire to ride his train into the face of the GOPe and political correctness. Would like to see both of them in office less than a year from now.
There's only one candidate who has a PROVEN record of swimming in the opposite direction in the GOPe stream. Just ONE. He's never been a pro-single payer health care system supporter. He's never been pro-abortion. He's never been for limitations on the 2nd Amendment. He's never been in favor of funding Planned Parenthood. He's never insulted a POW for getting captured, ridiculed a person who is physically disfigured, nor waded into bizzaro truther territory by accusing a former president of knowingly lying about such things as the Iraq war and the 9-11 attacks. His convictions weren't recently (and conveniently) arrived at. Constitutional conservatism is in his bones.
I agree with the author of this piece. Trump's not to be trusted. IMHO, a vote for Trump is even more dangerous than a vote for a Dem, because with a Dem, you already know what you're getting. With Trump, all you know is what he wants you to know at this juncture. Once he has his way with you (the American electorate), you'll find out what kind of deception you've swallowed hook, line and sinker.
There is a candidate who actually fits the description of all the things I listed above, yet he gets pass after pass after pass from the Republican voter. These are the same voters who extend not a shred of grace to any of the other Republican candidates, yet are willing to overlook all the liberal positions and downright rudeness of Trump. If anyone -- ANYONE -- would have told me in June that FReepers would be following Trump as if he were the pied piper, I'd have told them they were nuts. Now I'm the one who has to bear the embarrassment of too much optimism.
