Have heart. A victory like this one will energize many new people who can now see they have a chance against the machine. Never mind the fact that Dewhurst has damaged himself beyond redemption in addition to anyone who endorsed him.
I'm disgusted with some of the people who endorsed Dewhurst. I hope this is a lesson for Mike Huckabee, Michael Reagan, James Inhoffe. It's possible some of them didn't know Dewhurst was going to sink so low, like that blubbering mother ad, but some of them like Inhoffe came on board after Dewhurst had thoroughly established himself as a slimeball.
