I really liked Ted Cruz and his positions, Marco rubio was also interesting and sounds like someone who stuck out from a realistic perspective.
Wasn't a fan of Scott Walker, seems very mellow and making excuses relying on perceived success, Donald Trump seems like a troll and his history seems to show that, I think he causes more damage to the GOP . Rand Paul, after hearing his stances, he really didn't have much to say but after hearing him, don't like him either, Chris Christie reminded me too much of Bush.
I think it'll be either Ted Cruz or Marco rubio for me.
