I'm not aware of any leverage we have, at OSTP or within the federal government, over the science curriculum in Texas, other than exhortation. We can argue and we can beg and we can try to educate. But we have no authority to act.
Ah, the joys of federalism and division of responsibilities.
I hope that the Washington lot do not underestimate the value of exhortation, though. While it's clear that nothing will change the mind of someone like Don McLeroy, it might change the mind of some Texas legislators.
