Answer:
In presidential elections, I've noticed that third party voters tend to be more independent voters who haven't made a commitment to one major party. Third parties frequently receive support from younger voters. There is less of a pattern of votes for one single party because they have not participated in as many elections as older voters. In general, third party voters also have a hatred of the government. They are more likely to experience political disenfranchisement. They believe that the two major parties do not adequately represent their opinions. They support third parties in part because they actually agree with the candidate and his points of view and in part to oppose the two major parties.
Many, but not all, third party voters can be described by these justifications for casting a ballot. Both a long-term analysis of American presidential elections and short-term research studies of certain presidential campaigns reveal these trends.
