Massachusetts Governor Mitt Romney hits the radio airwaves today in hopes of stopping the cloning bill in the statehouse there. Listen to his ad here.

Gov. Romney, again, articulates a position I’m not 100-percent enthused about–those “surplus” embryoes from fertility clinics he talks about don’t need to be destroyed–but conversations about adopting embryoes will be totally moot point when Mass. opens the door to creating new embryoes, nevermind using ones already around, to use for medical research. So the choice about who to support in this Massachusetts battle is not a hard one for those who oppose cloning.

Romney does make the important point (besides the hardline he takes against creating new life to destroy for research) that rarely gets heard in the ad: That he is–as am I, as is everyone I can think of–for stem-cell research. It’s when we start talking embryoes where things get promblematic.
