Somehow, you've ended up saying that when educated citizens overwhelmingly support one governing philosophy, it's not only somehow bad for the educated citizens, it's also bad for the philosophy! That's a neat trick.
(btw, that philosophy -- american 'liberalism' -- would barely deserve the name in any other 1st world country)
You started off almost saying something, but i'm not sure your thesis holds ('...in a two party system, any group...') Take the converse. I could also say that the group of anti-intellectuals has completely affiliated themselves with the Republican party, damaging themselves and the Republicans. Same thing, right?
Anyway, you reminded me of the 'everything that happens is good for John McCain' meme, which might be worth researching. One particularly egregious example is here: http://www.balloon-juice.com/2008/07/29/life-imitates-farce/
cheers, and let's try not to bullshit ourselves.
