Paul really outed Rick on the vaccine issue and brought up that he signed an executive order mandating it. Not only did Paul mention it, but several other candidates commented and blasted him as well. Perry must have been PISSED on stage. Really his only response could have been resorting to mafia intimidation tactics.
I've seen it in several online youtube interviews, when Perry is asked about his "record" he always gets super defensive and physical, this will likely continue. We need some Guerilla type reporters at every Perry rally, meetup, and campaign stop to ask him nicely about his "record" and record his lovely responses!
