That, by definition, is what a single issue voter is. Yeah I am sure you have all sorts of con issues that you support but this single issue will define whether or not you vote for a particular candidate. Here is a question for you. If you had a choice between a candidate who embodied all the loony left had to offer yet was pro-life and a candidate that was a pillar of conservative thought yet was pro-choice, which would you pick? Don’t say it could never happen, just answer.
Still waiting to see dschapin’s answer.
In answer to your hypothetical question. If the conservative candidate was less pro-life than I would like but still supported many meaningfull restrictions on abortion - I would vote for him. However, if he supported abortion on demand like Giuliani does I could not in good conscience support him. I simply don’t want the blood of any unborn children on my hands. If the other candidate also was completely unacceptable I would vote for a write in candidate.
