More than Jack Kennedy and Lyndon Johnson? I doubt it.
That’s a good point. Johnson was dislikable (and vice-versa) on the order of Trump, and Kennedy was all superior Eastern-college guy like Cruz.
However, Johnson had long-time government experience and connections that were useful to Kennedy, especially in operating the nationwide Democrat election-fraud machine. Trump has fervent followers, but he doesn’t have anything to contribute to the nuts and bolts of a national campaign.
I read your posts and you are very clear-minded about what is going on. I support Cruz but am not Never-Trump. Cruz is a young man and is doing a very strong job building his case. I could see him taking all the support he has built to the convention and playing his way onto the ticket either as the nominee, or running mate, or into a place that strongly positions him for the future. I totally agree with your Kennedy / Johnson analogy from 1960. When power is at stake, deals are made, and Cruz is in a powerful position.
