According to Michael Freeden, ideologies define political concepts in terms of proximity. Otherwise, political concepts “make no sense on their own” (Freeden, 61). In the United States, the two dominate ideologies for the political system are conservatism and liberalism. Conservatism is obviously related to the Republican Party and liberalism is related to the Democratic Party.
For example, same-sex marriage does not mean anything by itself. However, if the political concept is put into proximity to the ideology of conservatism, it is defined as “unnatural” and therefore should not be made lawful in the United States (Freeden, 88). Put into proximity to liberalism, same-sex marriage is a social advancement and should be made legal.
However, party loyalty undermines the disclosure of political concepts to different ideologies. Party loyalty is a dominant aspect of the two political parties in the United States, and it destroys political concepts from coming into proximity with other ideologies other than conservatism and liberalism. If a politician is loyal to his party and thus ideology, then he is more likely to be promoted in his party. So, party loyalty suppresses other ideologies, because politicians are in the end trying to do what is in their own best interest: gaining power, money, and prestige.
So, without introducing other ideologies to help execute political concepts, political concepts are not able to evolve and change as fast into a better concept. Two heads are better than one, but three heads are even better, and so it is with ideology. Now, I am not saying that we should introduce other macro-ideologies like communism to help define political concepts but micro-ideologies would be beneficial (Freeden, 78 & 94). With more versions of a political concept being discussed, the more likely a better solution or decision can be made on that particular political concept.
