Rep. Paul Ryan (R-Wis.), New Jersey Gov. Chris Christie, Indiana Gov. Mitch Daniels and Sen. Marco Rubio (R-Fla.) have all said they aren’t running for president. But would one of these make the ideal No. 2 pick on the ticket? Tell me which you like (or if there is someone else I haven’t listed) and why (or if different potential vice presidents work with different presidential nominees.)

Remember all answers must be in by Sunday at 6 p.m. ET.
