Official Stop OBAMA Express!!!

I think that people should use protection if they don't want to get pregnant. I believe that being responsible prior to the act can avoid all of the drama surrounding that topic. But if the right to choose is protected under the constitution then why do republicans continue to try and oppress women on that issue? If the government can't even mention anything about gun laws, why can republicans continue their attack against women's right to choose??? This is what confuses me...
