Over at the New York Times, you can scroll over a map of the U.S. that provides you a state-by-state pop-up of how each delegation voted. And the Times also provides a way for you to email your senators and let them know what you think of their vote.
Pundits say that it is “unlikely” that there could be enough votes (just 3 more in the Senate) to override the veto. But if you scroll down a list of Republicans who in favor of expanding embryonic stem cell research–Orin Hatch, Bill Frist, etc.–it becomes clear that reason and compassion can cross party lines.
