Out of the three that you listed, I like Ted Cruz the most.
Polls that I’ve seen have Cruz in 2nd place a ways down but gaining. I expect that will change as they proceed to the Apr primary. Dewhurst has better state recognition due to his tenure as Lt. Gov., imo.
I agree with you on the name recognition point. One of the local readio stations had an interview with Cruz this morning and I listened to some of the interview as i drove to work. I was quite impressed with what I heard.
