Fiorina is not running for VP. She [knows that she] has nothing to contribute as VP, not being from a typical "Washington political class," with wide and deep connections on the Hill.
However... there is a very good chance that GOP VP spot on the ticket will be given to a female Hispanic Governor from New Mexico, Susana Martinez (changed party affiliation from Democrat to Republican in 1995).
Bet me. If Jeb! is the nominee, the running mate will be Rubio, Walker or Kasich.
