I'm not a big Perry fan, and being a life long Texan would pick Bachman over him, HOWEVER! What I think Matt is talking about is the executive order Perry signed requiring all girls in Texas entering the 6th grade to be required to take the HPV vaccine, which is said to prevent cervical cancer. Matt however, apparently didn't read far enough, as the House of Representatives repealed the executive order to a vote that to veto the law, would have been foolish on Perry's part. So in short Perry has killed no one, other than a coyote that attacked his dog, by using his concealed carry pistol while on a jog on a trail.
As I said, I am a life long Texan, and not a Perry fan for president, but one should not make such outrageous claims until fully researched. He has enough negatives, without making them up.
If Bachman survives the primaries, I will most likely support her, unless I hear something I have not found on her.
