Because Cruz has never managed anything, I don't think he has the skill set to be the president, a job of constant decision-making. Cruz is used to studying, talking and debating. There is no decision-making required on a daily basis in the Senate.
And that's why Trump is more suited for job as president. He has made himself successful and wealthy making executive decisions in his companies. He knows that part very well. As George W. Bush once said, "I'm the Decider-in-Chief."
But I think the perfect job for Cruz has a "Help Wanted" sign in the window right now. President Trump's first act in Oval Office should be to nominate Cruz to fill the Supreme Court seat vacated by Scalia's passing. This scenario would be a win-win-win solution for everyone.
Trump would be seen as magnanimous in selecting his fiercest opponent in the primaries to such an important position. Cruz would be in a lifelong position, not requiring reelection where he can put all of his positive skills and attributes to good use. Speaking somewhat tongue-in-cheek, I'm sure the Senate would gladly give their consent quickly, knowing that the burr in their saddles, Mr. Cruz, will no longer be their constant irritant on the floor of the Senate and they'd be rid of him. The conservatives would get their justice to replace Scalia.
But what do I know.......
I agree with everything you said I would love to see Cruz on the Court but I just don't see how he could be confirmed.
Not a single Dem will vote for him and most of the GOPe can't stand him. Agreed they may begrudgingly vote to kick him out of the Senate but there are a number who will never vote for him.
Will Trump want to start out with a nomination and run the risk of loosing in his first fight?
If he wins in a landslide he may just want to put everyone on notice that he is in charge. His unpredictability is one of his strengths.
