I hope you're right. What worries me is that the alienation of the GOP from science will entail the long-term ascendancy of leftism in this country, with all that that entails.
I am not advocating the following, just throwing it out for your input
If things get worse...
What if a fair number of science supporting conservatives were to join their local democratic party and form "Democrats for a sane fiscal policy" or some such. Run a candidate or two. Ally with the local Democrats for Life (they really exist and are quite vocal, but they are not just pro-life, they are anti-war, so it would depend on the international situation)
IOW...coopt the democratic party to save science. Sneak conservative values in one at a time or return to supporting Republicans as soon as the worst of the attack on science is over.
