That's the point. Evangelicals are usually grouped in the single issue or just social issue column. Give them scraps as incentives and they show up in droves to vote. Piss them off and they usually stay home.
In all of the candidate speeches in the tight races, listen to the words. You'd think Gay Al, Queer Eye, and RuPaul were taking over the country if the Dems win. In order to turn out that element, the candidates have been instructed to play up this gay rights, gay marriage, abortion mantra. Most of these candidates aren't even touching Iraq or Bush, once deemed the strongest points. They've diverted to some secondary issues to ensure as many voters as possible are energized.
A book like this topped with the appointment of the gay ambassador on AIDS issues doesn't bode well for appealing to the Religious Right. When you have Condoleeza Rice introducing a new ambassador who is gay, his partner, and his partner's mom (introduced as the mother-in-law), these evangelicals begin questioning if the GOP is all talk.
