Marco Rubio is an enemy of liberty. Why are you so obsessed with FreedomWorks scores? Oh I got it, because they ignore everything except fiscal issues.
FWIW, Rubio and Crist were both endorsed mostly by establishment figures, and Rubio has always been an establishment guy. The whole idea of him being some sort of grassroots candidate is pure fantasy.
Rubio was endorsed by: Romney, Huckabee, Giuliani, Jeb Bush, Pence, Ryan, and Santorum. Don't try to pretend that one is the estalishment and the other isn't. They're both anti-liberty scum. As is this new guy, who also got the Cheney/Pence/Ryan endorsements, and whose dad is running an anti-Amash PAC.
If you want someone who, at best will be Marco Rubio, then go join Ricketts' campaign team.
