I'm certain there are some pro-Life Libertarians out there, but they are just not what I'd call mainstream (L)'s, if you know what I mean.
Most libertarians I know are pro-life. It's one thing to be pro-life and another to believe the government should get involved in the abortion business. Or to put it another way, if you really want to stop all abortions, just convince everyone to be pro-life. Then no one will get them, right?
Oh, I forgot. Pro-life (at least for the first trimester) has never been able to win in the marketplace of ideas, so you marketplace losers need the government to subsidize your viewpoint. You guys are a bunch of viewpoint socialists.
