It's not bad enough
See his Christmas Opinion piece on this matter and several outraged responses here. Santorum claims to be a reasonable man, but shows his flat-earth roots:
Evolution should be taught as a scientific theory that is open to scrutiny, not as sacred dogma that cannot be questioned.Follow my links at the top of this page if you want more about the weakness of these claims. Or just accept that natural selection is as much a theory as gravity is; it's mighty powerful and widely taken as a given for its proven predictive value.
But is there a real scientific dispute? Absolutely. [blahblahblah]
