The creationist/ID camp I think is as damaging to the credibility of conservatives as the Gay marrage camp is for the Dems.
Fortunatly for us, it looks like we may be shuting down the anti-science crowd since Dover, while the Dems may be stuck with the gay marrage folks for awhile because they're supported by the MSM.
I believe this is true. There are still school boards that want to push creationism/ID, as in Kansas, and also the occasional state legislator, as in SC, but when they talk to their lawyers, after the lawyers have reviewed the Dover decision (Kitzmiller et al. v Dover Area School District et al.), very few of them will go all the way. The Dover decision is almost certainly the death of ID's attempt to sneak into science classes. And the total wipeout of the Dover school board in the recent election is -- we can hope -- the end of ID as a republican issue.
