We right libertarians of course will not lose any sleep over gay marriage, because we do not believe that the government should be in the business of marriage in the first place, marriage after all being a covenant among God, a man, and a woman.

As for “libertarians” who support the “right” to an abortion, again, they can call themselves whatever they want, but that does not make them libertarian. Without the right to life, all others seem pointless to me.

Yes, indeed, the Libertarian party will remain fringe so long as it continues to be dominated by what you refer to as left-libertarians, and what I have always called liberals or libertines (they want drugs legalized because they want to use them, not for any other reason).

However, even if we can shed these liberals, Senator McCain has ensured that the party cannot rise to prominence. Campaign Finance laws are meant to, and in fact, accomplish only one thing, to ensure that additionaly parties cannot obtain the funding (or at least make it far more difficult) necessary to rise to prominence.
