1) You might recall the comments of candidates Akin and Mourdock last year. They told the women of America that if they had their way with the abortions laws, pregnant rape and incest victims shouldn't be allowed legal abortions. Good way to attract female voters GOP.
2) Elements in the GOP that want Christian creation myths taught in science classes. Broun's comments are just one of many examples of GOP pols beclowning themselves over evolution and the big bang theory. These type of GOP pols frighten away intelligent, educated voters.
3) Social conservatives want to impose their religious value system on everyone via politics. Problematic in this day and age.
That is the brand that is out there. Perhaps rebranding is in order.
