I'm embarrassed for the nation that a commercial like this is even necessary, and that there are large numbers of ignorant, low-information nutballs out there to whom the truth of this matter in the 21st century isn't patently obvious.  But it is an incredibly powerful ad, and kudos to Michael J. Fox for making it and for being willing to bring down the vituperation of the right wing hate machine upon himself over something for which he is most vulnerable.  (The McCaskill4Missouri campaign, who put the YouTube up, has obviously scrubbed the most despicable wingnut comments.  But you get the gist from reading the justifiable outrage they inspire in others).

My favorite comment:

And yet, if someone invented a way to burn blastocysts into gold, Bush and his greedy cohort would run after them with flamethrowers.

I hope the ad helps Claire McCaskill -- in a rational world it certainly should.  Just spare me the whinging of the "every sperm is sacred" crowd.  I'm not in the mood for it this week.
