Realistically, I think I’d rather see Walker in top slot - he’s got Executive experience because he’s a Governor; Cruz would get seasoned as the VP and be ready for the NEXT go around.
I think Governors do better than Senators in the POTUS slot.
Just my two cents...
Ordinarily, I might say the same, but DC is a different place than a state capital, and we need someone who has become quite familiar and disdainful of the corrupt cesspool, hence Cruz at the top.
Think of it like the 1920 ticket. OH Senator in the #1 slot (Harding), MA Governor in #2 (Coolidge). They both did a helluva job. Harding resolved the Wilsonian recession in record time by cutting taxes and government. Reviled by leftist historians, he is actually one of our best Presidents in my personal estimation. Cruz could follow that model.
