Mainly because Democrats tent to be more educated about this issues.

I used to post on a forum dominated by Bush supporters. They totally defended the use of GMOs and opposed food labeling. Bush Sr was a huge Monsanto fan, even used to dress up in a White Coat and pose at their headquarters trying to improve their image.

People are not just anti-something for no good reason, especially Democrats. They are opposed because they are knowledgeable and do not buy the propaganda perpetrated by these corporations.

Monsanto is one of the most hated Corporations in the world, and finally is beginning to feel the backlash of countries all over the world as more and more of them are banning their poisonous products.

The recent WHO finding that an ingredient in their products may indeed, as alleged for a long time, cause cancer, has upped the opposition around the world, to the use of their products.

AND the findings that their insecticides may be contributing to the disappearing honey bees, has caused them even further opposition.

They are attempting to control the World's Food supply, are hated world wide, and DU has always been anti-GMO as long as I have been here.

Except for a handful of people.
