I'd like Sessions as VP, but can't imagine how the sewer AKA US Senate gets cleaned out if he isn't there. So I'll say:
Sessions for Senate leadership role
Santorum for VP
Palin for Secretary of Interior
Rubio for AG
Huck for Press Secretary
Dr. Carson for Surgeon General
That is a great idea -- he would be very good in that slot
Interesting choice. Santorum is the only man running who's tougher than Trump on immigration. Santorum's career is over and for any normal candidate I'd disqualify him for VP because he's so unpopular in his home state. Instead I'd look for someone who brought more votes to the ticket. But Trump is so strong he's not likely to need any help. It would also reassure Christian voters.
He's also one of the only well known Republicans who, like Trump, opposes "free trade."
