The Pew Research Center for the People and the Press has an interesting test that will pigeon-hole your ideological predilections for you. As with all such tests, some of the questions are irritating because neither of the options given accurately describe one's position, but even so, the overall results seem pretty accurate. Once the test is completed a link takes you to a page which describes the typical person in your political niche, of which there are about seven or eight.
Viewpoint, it turns out, falls into the "Enterpriser" category.
