a third party candidate的准确译法

The United States is often thought of as functioning under a two-party system。In practical effect this is true:Either a Democrat or a Republican has occupied the White House every year since 1852。At the same time,however,the country has produced a plethora of third and minor parties over the years。For example,58 parties were represented on at least one state ballot during the 1992 presidential elections。Among these were obscure parties such as the Apathy,the Looking Back,the New Mexico Prohibition,the Tish Independent Citizens,and the Vermont Taxpayers。Third parties organize around a single issue or set of issues。They tend to fare best when they have a charismatic leader。With the presidency out of reach,most seek a platform to publicize their political and social concerns。具体例子见网址
