I am not in the polling business. That being said, I am pretty confident in saying that, yes, most libertarians are pro-choice. Thanks for bringing up Ron Paul. He gets a 50% rating from the National Right to Life Campaign. Plenty of people see nothing wrong with abortion, but still want to see the issue apporpriately settled by state legislatiures.
I would add that most libertarians I have met either believe that the government at least knew about 911 before hand, or else they are unabashed truthers.
If you’re as pro-life as you claim to be, you’d invest more time trying to change your own party’s positions on life issues, and less time trying to make a different party more like your broken one.
