Rodeo, I still don't buy your argument that a federal policy coupled with funding (or the lack of same) is "regulation." The State's still had a choice whether or not to take federal money in the speed limit example above. That they might chose not to is a decision based on the State governements' willingness to raise funds for road projects through taxation. You take this as regulation; however I submit that what you're seeking is "entitlement."
Labs involved in any research that receives federal funding with policy strings attached have to make a business decision. Federal funding for this research
is not an entitlement, it is a means to bootstrap research. Your doors shuttered comment is pure hysteria. Labs must either use the limited stem cell lines currently approved for federal funding or seek fundng from other/private sources. And citizens (e.g., MJF, et al) can (should) try to influence federal policy through public campaigns and voter action. In a couple of years, the federal policy regarding funding stem cell research may shift dramatically. I'm all for it.
And Rush L. is a gas bag, druggie without scruples.
