Sen. Joe Biden has charged:
"If you care about [children with disabilities], why don't you support stem cell research?"
Where to begin...
Republicans do not oppose stem cell research. (Some) oppose embryonic stem cell research. Adult stem cell research is as popular as ever among Republicans and conservatives.
What's the difference? Well, the former destroys a tiny human being, and the latter has shown actual results.
And neither would do much to help a whole host of birth defects including the one currently in the spotlight -- Down's Syndrome.
