But the question is what specific duty or function of the presidency would Cruz be unable to accomplish that Walker could, based on the differences you describe?
I say none. In fact, his language and his actions show him to be more conservative than Walker.
I agree. My point is that just focusing on the ability to get votes Walker, being a governor and having a significant record of accomplishments, (especially compared to the Hildabeast) would be better at the top of the ticket.
The main idea is to WIN.
