One thing I'm not certain I understand are the libertarians who look at Paul's pro-life stance on abortion as a reason not to support his candidacy.
Yes, he probably would favor laws restricting abortion, but only at the state level, and that's not the level of office he is running for. Yes, he would want to appoint Supreme Court justics who would overturn Roe v. Wade, because he believes that abortion should not be an issue to be decided federally, but then again that was also the position of Harry Browne, the 2000 Libertarian Party nominee for the presidency. (The major difference is that Browne did not want state-level regulation of abortion either, but he didn't think it was within the federal government's legitimate power to restrict a state from doing so).
For those who did not support Browne in 2000, that would make sense, but for people who supported Browne in 2000 to use abortion as an argument against supporting Paul suggests at least that they need to articulate why they differentiate the candidates.
That is all.
