Cruz may not be interested, and there is, indeed, a lot of water under the bridge, but you’d be surprised by the way that a pol can rationalize a complete course correction.
Don’t get me wrong, I like Cruz a lot. I donated to his campaign when he declared, and I’ll be thrilled to vote for him (as opposed to Kasich, Rubio, Jeb, [fill in the name of any Establishment RINO]).
But I don’t think that Trump will take Cruz as Veep, not with the issue of Cruz’ place of birth. Note that whatever your view of that issue may be, Trump IS correct that the Dems will sue on it - and that kind of a distraction will not help the ticket win in November. But a deal doesn’t necessarily have to include the Veep position. Maybe they’ll cut a deal in which Cruz is the Solicitor General (I’m pretty sure that Christie was already promised the AG spot), and get to pick ALL of the federal judges that Trump nominates - Cruz vets them, comes to Trump with his top 3 choices for each position, and POTUS Trump picks one and does the nominating. Later, Cruz gets put on the Supreme Court - perhaps even as the CJ, after Roberts is forced by them to resign “to spend more time with his family” or some such thing. Being the Chief Justice for the next 40 years ain’t exactly settling for 2nd best - he’ll still be active long after Trump is dead and gone.
I like the way you think
