Quizplus · Accepted Answer

The dominant role that party activists play in the nominating process of both parties is the factor that contributes the most to the ideological gap between political parties. Primary elections and caucuses, which are dominated by highly motivated party activists, play a major role in determining the nominees for each party. These activists tend to have more extreme ideological views than the general electorate, which can lead to polarization and a widening ideological gap between the parties.
