The Economist, in the same issue it reviews me and Andrew Sullivan, takes up the plight of the American libertarian:

AMERICA may be the land of the free, but Americans who favour both economic and social freedom have no political home. The Republican Party espouses economic freedom—ie, low taxes and minimal regulation—but is less keen on sexual liberation. The Democratic Party champions the right of homosexuals to do their thing without government interference, but not businesspeople. Libertarian voters have an unhappy choice. Assuming they opt for one of the two main parties, they can vote to kick the state out of the bedroom, or the boardroom, but not both.

The piece goes into the new Cato Institute study on the libertarian vote. Cato pegs it at 13 percent of the American electorate, which is in line with most estimates of between 10 and 20 percent.
