>> 2016 I’d go for the Double R: Rubio - Ryan <<
Apart from the fact that 2016 isn’t a POTUS-election year, I think you’re way off base:
In spite of the fact that Rubio and Ryan have absolutely sterling qualities in terms of their policy stances, their obvious high IQ’s and their overall “presentability,” neither man has demonstrable executive experience.
Therefore, just like Bachmann, De Mint, Pence and other “congress only” critters, they don’t qualify in my book. Give me a successful governor or successful corporate CEO, and then I may be with you.
