Left–right political spectrum
The terms left-wing and right-wing are widely used in the United States, but as on the global level there is no firm consensus about their meaning. The only aspect that is generally agreed upon is that they are the defining opposites of the United States political spectrum. Left and right in the U.S. are generally associated with liberal and conservative respectively, although the meanings of the two sets of terms do not entirely coincide. Depending on the political affiliation of the individual using them, these terms can be spoken with varying implications. A 2005 poll of 2,209 American adults showed that "respondents generally viewed the paired concepts liberals and left-wingers and conservatives and right-wingers as possessing, respectively, generally similar political beliefs", but also showed that around ten percent fewer respondents understood the terms left and right than understood the terms liberal and conservative.
Christian right
Evangelical leaders like Tony Perkins of the Family Research Council have called attention to the problem of equating the term "Christian right" with evangelicals. Although evangelicals constitute the core constituency of the Christian right, not all evangelicals fit the description and moreover, a number of Roman Catholics are also members of the Christian right's core base. The problem of description is further complicated by the fact that "religious conservative" may refer to other groups. Mennonites and the Amish, for example, are theologically conservative, however there are no overtly political organizations associated with these denominations.
