Rubin finds much to admire in both. Each has real accomplishments to point to with pride. Neither is tarred with much scandal. She hints at a ticket with both on it, but I can't imagine either wants to be VP to a youngish president.
My guess: Walker gets the nod, he more closely resembles the modal Republican base voter than Rubio. Walker's main problem, Democrats would rather run against him than Rubio, who might cost them a significant share of the Hispanic vote.
