In short, Dems - Evil.
I'm talking about the average "soccer mom", Oprah watcher, or daytime radio talkshow callin who wants stem cell research so badly and hates mean old Bush for not allowing it (or something - few of these people seem to actually know what exactly Bush did vis-a-vis stem cell research. I think most think he banned it.)
Trust me, such people wouldn't know a stem cell from a Duracell.
