I think Cain would be a better choice for a running mate. IAC, she still has not announced. Although it does look like she is running for something. A fast moving target, hard for the Establishment to do more than wing her right now. Every time they try to lead her, she darts off in a new direction.
Palin/Cain 2012 & 2016. Cain/West or Cain/Bachmann 2020.
