Contrary to the thread on the rec list (and the Obama response), the GOP platform doesn't call for banning all research, public or private. The relevant text is this (pdf),
Taxpayer-funded medical research must be based on sound science, with a focus on both prevention and treatment, and in accordance with the humane ethics of the Hippocratic Oath. In that regard, we call for a major expansion of support for the stem-cell research that now shows amazing promise and offers the greatest hope for scores of diseases — with adult stem cells, umbilical cord blood, and cells reprogrammed into pluripotent stem cells — without the destruction of embryonic human life. We call for a ban on human cloning and a ban on the creation of or experimentation on human embryos for research purposes.
The paragraph appears to be talking about public funded research only - it never explicitly mentions "private" funding - you have to read into it to say it's calling for a ban on private funding.
Without such embellishment, the platform is still more extreme than the current Bush policy, so we can still use this against McCain, without resorting to a rethug spin tactic (lie).
Since when is NRO a trustworthy source?
