But what earthly reason would Cruz have for accepting the offer?

Cruz would LEAP at the opportunity if given it. It would expand his power and save his career.

But you're right, it's not going to happen.

Cruz would LEAP at the opportunity if given it. It would expand his power and save his career.

What power? Which career? He could accumulate more power and have a more meaningful career in the Senate. The vice-presidency offers neither. Cruz wants to be president. He's not going to get there as Trump's vice president.
