Here's an ad Missourians may hear more than once before election day.

Actuality:  RADIOAD.WAV

Run Time: 00:06

Description:

The woman is an actress, the man is a real doctor. He's also a board member for a group who opposes the constitutional amendment voters will consider this November. If passed, the amendment would ensure that all forms of stem cell research allowed under federal law would remain legal in the state. 

Jaci Winship is the executive director of Missourians against Human Cloning - the group that produced the radio ad. She says the ad is meant to counter what she calls the false claims of groups that want Missourians to vote yes on the amendment.

She says it's her organization that has scientific evidence to support its message, not the initiative's proponents. Donn Rubin, the chairman of the Missouri Coalition for Lifesaving Cures disagrees. He says it's the opponents that don't have scientific backing.
