David Boaz and David Kirby have continued their research on the influence of the libertarian vote in national elections:

This year we commissioned a nationwide post-election survey of 1013 voters from Zogby International. We again found that 15 percent of the voters held libertarian views. We also found a further swing of libertarians away from Republican candidates. In 2006, libertarians voted 59-36 for Republican congressional candidates—a 24-point swing from the 2002 mid-term election. To put this in perspective, front-page stories since the election have reported the dramatic 7-point shift of white conservative evangelicals away from the Republicans. The libertarian vote is about the same size as the religious right vote measured in exit polls, and it is subject to swings more than three times as large.

Based on the turnout in 2004, Bush's margin over Kerry dropped by 4.8 million votes among libertarians. Had he held his libertarian supporters, he would have won a smashing reelection rather than squeaking by in Ohio.

President Bush and the congressional Republicans left no libertarian button unpushed in the past six years: soaring spending, expansion of entitlements, federalization of education, cracking down on state medical marijuana initiatives, Sarbanes-Oxley, gay marriage bans, stem cell research restrictions, wiretapping, incarcerating U.S. citizens without a lawyer, unprecedented executive powers, and of course an unnecessary and apparently futile war. The striking thing may be that after all that, Democrats still looked worse to a majority of libertarians.

Because libertarians tend to be younger and better educated than the average voter, they're not going away. They're an appealing target for Democrats, but they are essential to future Republican successes. Republicans can win the South without libertarians. But this was the year that New Hampshire and the Mountain West turned purple if not blue, and libertarians played a big role there. New Hampshire may be the most libertarian state in the country; this year both the state's Republican congressmen lost.

Will the Democrats reach out to libertarian voters? It remains to be seen. I don't think they will. They've embraced the left and the myth of FDR, that it is government that makes this a great country. I think it is a possibility in some parts of the country. Georgia is a place that some free-market Democrats are opening up to libertarian ideals.

Ultimately the only home for these individuals is the Libertarian Party.
