For most of us, it’s Cruz/Trump/Paul/Carson/Rubio, in some statistically insignificant order from 95%-85%, depending on how one answers levels of importance.
It’s a shame these guys, except for Cruz and maybe Carson, feel the need to attack each other personally. Each time, they hinder conservatism.
I agree. Some people say candidates need to do the trash talk and personal attacks in order to win votes. If that's true, it reflects poorly on the voters.
