What's the deal with prolife politicians not being able to talk about stem cell research?

Is it me or does it seem like every other week or so there is a new prolife political candidate who is unable to give a decent answer to the media on where they stand on embryonic stem cell research or human cloning.

The most recent is U.S. Senator Jim Talent. But in the past couple of weeks Maryland's Lieutenant Governor Michael Steele , Pennsylvania gubernatorial candidate Lynn Swann and Michigan gubernatorial candidate Dick Devos have all failed to properly explain their position on embryonic stem cell research.

Maybe it's because they don't want to take concrete stands on controversial issues before voters get a chance to know them. Maybe it's because they're scared of how the media will portray their response. Maybe they want to appear thoughtful. To me, they come of as waffling willows who are unable or unwilling to stand up and explain what they believe.

If there are any aides to these politicians out there, please have your candidate read this paper from Scott Klusendorf and then have them review some of the other resources he provides at the end of the paper. Being able to provide a rational and thoughtful defense for your beliefs is exponentially more impressive than saying, "I'll have to think about that and get back to you."
