I don't discount Cruz. And bad as some think he is, every alternative seems much worse. Kasich, Rubio, Carly, Ryan, Carson -- no thanks. Walker? To walk things back, all Trump and Cruz would need to say is that, based on re-evaluation of present facts, the ticket makes sense.
It is surprising, though, how few Vice Presidents have ever been elected President in their own right without first having suceeded to the office by the death of their predecessor.
John Adams 1796
Van Buren 1836
Nixon 1968 (after retiring from Vice-Presidency)
GHW Bush 1988
So, if a person aspires to become President, the Vice Presidency does not seem such a good platform and nowadays seems usually to be reserved for an older has-been.
In Cruz' case, he is unlikely to find a better platform. Especially since he has no great executive or wartime experience or bona fides. He needs mentoring. Given Trump's age, Cruz would not likely ever have a better bet.
There is a kind of mindset that cannot be content unless it is ruling, It is not content to have things unless it can use things to arouse worship or envy. It cannot abide not subjugating and lording over other people.
Such a mindset will connive to import easy dupes and prey, and then use them to rush and rule every decent, independent minded person. That mindset is firmly ensconced in the establishment uniparty. If Trump kicks it out of the Republican Party, the Dem Party will become a den of pure evil.
The upshot will be ugly. It will entail a bloody fight for ultimate dominance, essentially to use the Dems to entice and import diverse dupes in order to restore slavery or, at a minimum, peonage. A war is coming to make us offers that we will have to confront, because we will not be able to refuse.
It is only by ignoring the war that is definitely coming that so many people are able to fool themselves into believing that secession will not become necessary if any decency is to be preserved. A stream of plagues will simply not be avoidable. The slower we are to learn, the more lengthy and onerous the plagues will become: Disease, disorder, breakdown, currency failure, infrastructure failure, system failure, looting, invasion, destruction, suffering, starvation, moral failure. IOW, all the rewards that are fit for Prog Heaven.
Ultimately, currency is backed by nothing more than conditioned social trust. As faith is broken, trust is forfeited, and hope dissolves in diverse perversions. In such a state, currency is profaned to such a point that it simply cannot sustain or save a society. Ultimately, financial libertines are subhumans that are simply unsuited to any decent society. They are spiritually, morally, and intellectually bankrupt to the point of being the very harbingers of hell. Read Gary Aldrich's Unlimited Access.
Meanwhile, moral visionaries will be ignored, and everyone will come to ignore all traditions and mores as "white hangups." And so everyone will do as pleases. Judges 17:6 -- King James Version: In those days there was no king in Israel, but every man did that which was right in his own eyes. Prog Acme 17 to the exponent of 6: In those days it would come to pass that there was no gender and no innocence, and everyone exhibited and stroked their genitals to every person and child, and there was no shame, moderation, loyalty, privacy, decency, or truth in them. Evil, thy name is "Clinton Foundation." And so the Pope will lie down with LGBT-OMG-WTF-BBQ (stolen from Quantum Electronics Dude).
All this noise about Trumpbots and Cruzbots! Insanity. It's hard to say which side has been most deranged. It's also hard to say which is most short sighted: Progs or Birthers.
There were always only two anti-establishmentarians: Trump and Cruz. Either would make a much better President for a representative republic than anyone else available. But their supporters, instead of respectfully advancing the issues, formed circular firing squads. Who "started it?" Much of it began when Trump enticed his minions to play stupid birther games. And they totally snapped and swallowed the lure.
I much want to preserve a representative republic. But with this kind of rampant insanity, I regret that I may be wrong. It may well be that our nation has become filled with the kind of mindlessness and liberty-illiteracy that make preserving the republic as anything more than a charade an impossibility. The Crony-Commie axis for creating a system of Morlochs and Eloi may have made its vision a self-fulfilling inevitability. The insanity of 1939-45 beckons. God help us.
