are most obgyn's against abortion or something? i find paul's stance to be rather at odds with his professed libertarianism.
I have no idea what the statistical view of this demographic is, so in hindsight I guess that was an unfair/misleading attachment.
The term "libertarian" is really a vague umbrella term for dozens of different political philosophies. The primary source of confusion stems from the difference between Libertarian and libertarian (Capital L = the Libertarian Party specifically). Obviously, socialist-libertarians, anarcho-capitalists, and minarchists, for example, will vary wildly in their beliefs, even though they're all technically libertarians.
The main difference in opinion among libertarians on abortion comes down to a disagreement over the point at which an unborn child is "granted" individual rights. For example, Ron Paul believes that life begins with conception, and that a fetus immediately has individual rights to life, liberty, etc. Others argue that an unborn child is not an "individual" until it has reached a stage of viability outside the womb. While (hopefully) every libertarian attempts to apply the non-aggression principle to each issue, this discrepancy in opinion makes reaching a consensus difficult.
Gary Johnson was allowed to participate in the first two GOP debates, and I believe he was given 6 questions total.
