Well, it certainly doesn't make the republican party innocent, or pro-life, or pro-christian for that matter. The republican party, like any political party is made up of businessmen, (they're not worried about the sanctity of life). Their positions are their investments, which is why they follow the party line. Oh, do you think they just happen to think alike? Corporations and Organizations shelve out big bucks and big votes lobbying for their collective support. They're only supporting the bill because during election time they get some fo the largest support from sincere devout pro-life Christians (i'm not saying that perjoratively since I am pro-life as I see it). And this bussiness about saving the lives of the unborn... where was their outcry when a republican president was bombing some latin american countries in the 80's? Oh, they were not American, I guess their heathen lives didn't count... How many pregnant women do you think are going to die in the war in Iraq? Think the vast majority of the women in Iraq are barren? Think again....
No political party is pro life since they all politicize life itself.
