I would have been really surprised if they had. Murkowski is not at all a libertarian. It would have been strikingly cynical if they had nominated her to run against the Republican candidate who is more libertarian than she. The Libertarian Party is all about putting ideological purity ahead of practical politics (for example, if a tenth of those who voted Libertarian in the 2008 Minnesota Senate race had voted Republican instead, we wouldn’t have nationalized health care today), so it wouldn’t have made a lot of sense.
