This is one manipulative television spot. Although I'm afraid it indulges in some serious scientific hype - stem cell cures for diabetes and Alzheimers remain a distant dream - it effectively humanizes a scientific issue. If we are ever going to get Americans to care about the politicization of science, then I'm afraid we will need more inflammatory ads like this one. The sucess of Rove rests on a single truth: you win elections by going after the amygdala. What gets voters to the polls is their visceral feelings, especially when they are tinged with fear.
That sounds anatomically confused.
Good point. I've modified the post. Thanks!
