Badger,
Dave Weldon & Dan Burton have been even more vocal about this over several years. This isn't a partisan issue. Frankly, I'm surprised that this isn't more of a conservative issue. Giving poison to our kids on purpose(not to mention the third world countries that are currently receiving ALL mercury laced vaccines from us) is no better than abortion in my humble opinion. Keep in mind that this mess started in the Clinton years.
It is an example of the "Hill-Care" we will all get if we do not work very hard.
