Missouri voters have narrowly approved a measure sanctioning embryonic stem cell research in the state. The amendment to the state constitution received 51% of yesterday's vote after supporters waged a $30 million advertising campaign that included celebrities such as Michael J. Fox.

And I believe we have Rush Limbaugh's comments were instrumental in the passage of this measure.
