Ask yourself those questions.
You accepted Mitt as your representative. I just can’t do that.

I am not happy with Romney, but I am sure that on some issues such as abortion Obama's actions would result in many more abortions, particularly for later term fetuses. Thus, as much as I am unhappy with Romney, I know any action I would take to give Obama another four years is wrongheaded. Additionally, Obama would appoint justices to the Supreme Court who would be more pro abortion.
