I don't use the pro-life - pro-choice issue to cast my vote.
I generally agree, however, I would look at the actual positions of each candidate.
Suppose that we were talking about elective cosmetic surgery, a nose job.
One candidate said: "There is an absolute right for a person to have a nose job. A 14 year old should have a right, on his own, without his parent's consent or permission of a judge, to get a nose job." I probably would not vote for that candidate.
Another candidate said: "Cosmetic surgery should be illegal. No one should get a nose job, unless their it affects his breathing to the extent that it's life threatening." I probably wouldn't vote for him either.
It's the extremes that bother me.
