It has not passed the senate. This is the Virginia House bill that has generated so much controversy. Get your frickin' facts right.
The point isn't for it to be medically necessary; the idea is that if a woman considering an abortion sees that there is something inside her uterus with a beating heart etc etc she'll change her mind. I don't know if that's true but whatever. That doesn't make Republicans horrible human beings. In fact, if they truly believe that abortion is murder, and by and large they do, then anything that stops some abortions would make them saints from that worldview.
Stop being so histrionic. See the other side's perspective a little. It's instructive.
EDIT: I just noticed that this bill was sponsored by a woman. I guess if this is a war on women, it's a civil war then, eh? Christ people need to tone it down.
