Why libertarians have lost their influence in the political debate:
Perhaps the most interesting fact in the Pew survey, however, was that less than 6 in 10 libertarians voted for Bush in 2004. While few libertarians seem to have deserted the president between 2000 and 2004, they are split roughly evenly between the two parties. The Pew survey finds 50 percent of libertarians identifying as Republicans, 41 percent as Democrats.
Given that libertarians' traditional home has been in the conservative base of the Republican Party for about five decades, as part of a strained partnership with social conservatives, their almost 50-50 split between the two parties today is big news.
According to Pew's "political typology," libertarians used to be one of three groups that made up the Republican Party, along with social conservatives and economic conservatives. But, since 1994, they've been replaced by a group of voters Pew has called Populists, but most recently renamed Pro-Government Conservatives. In essence, it would seem, these Pro-Government Conservatives -- about 10 percent of the electorate, largely female and southern, and equally at ease with universal health care and banning controversial books from libraries -- are squeezing libertarians further and further toward the fringes of the GOP.
It's astonishing, really, that libertarians have split themselves almost 50-50 between the two major parties. If they both advocate big-spending government, I suppose it doesn't really matter much who libertarians let themselves be marginalized by.
