Cain is one of only two candidates who have refused to sign the Susan B. Anthony’s pro-Life pledge
If you've read Cain's response to this, you would realize that his refusal to sign was based on one of the bullet points on the pledge being unConstitutional in regards to the President but he did release that he agreed with the platform.
All this shows is that Cain takes pledges seriously, not just sign them for political brownie points. Would you rather have someone as principled as Cain or someone who signs things blindly for brownie points?
