Dewhurst lost because he was a state-level version of McConnell/Boehner. A deal-making drunk who saw his role as holding back the people from control of their government. He was more allied with the TX ‘Rats than with the bulk of his own party.
*Bingo*! I love Ted Cruz and it pains me to see so many piling on. If Cruz isn't the nominee and Trump goes on to win the presidency, I hope Trump will grow up and solicit Ted's advice on picks for the Supreme Court since he knows all of the true constitutional conservatives and would give their backgrounds the necessary scrutiny.
Cruz would also be a great Attorney General and at least we know our TX governor, Gregg Abbott, would appoint a true conservative to fill the Senate vacancy. I just don't know if Trump is unforgiving enough to put our country's best interest ahead of his ego to recognize Cruz as a true asset.
