I was working in the Texas State Republican Party while Dewhurst was Lt. Governor. He gave money to help pay for my traveling Texas instructing in the Texas Election Law to lawyers/County Chairmen/Election Judges/Clerks. I was in his campaign office one year (not the year Cruz ran against him), and Dewhurst had money.
He wasn’t terribly effective as the head of the Texas Senate. We would have had Voter ID years before we did if he had not stopped that vote coming up when we had a majority in the senate that day. The Party was very angry when he would not let that vote come up.
Believe me, Cruz is a much stronger conservative than Dewhurst. I do applaud Dewhurst for telling the truth about Cruz now.
