A measly 5 percentage points from "shoving religion into classes nationwide"? You're making the EXTREMELY questionable assumption that "the know-nothings and American Taliban (dominionists, christian reconstructionists, etc) " are: (a) near, if not in excess of, 51% of the voters, & (b) unified & organized enough to pursue a common agenda. As best as I can tell, the largest & best-organized religion in the US is the Roman Catholic Church, which is a little above 20% of the population, & has no beef either with evolution or the value of pi. The fundamentalists are largely in the Evangelical Protestant wing of Christianity, which is much more given to being a bunch of independent congregations, & not necessarily united beyond a few general doctrinal principles. And, despite the best efforts of the last 40 years, school curricula are still largely determined at the state or local levels; your illusory "dominionists" wouldn't be able to advance their doctrines too far, even if they do take over the US Department of Education. And, given the suspicion & resentment many Christian fundamentalists have to the national government, their first reactions might be to gut those federal programs anyway, making it quite difficult for anyone to easily achieve dominance over the nation's schools.
