@Jaxk I am glad that you are lucky enough that your views align quite well with the overall Republican ideals. I, too, am a Democrat for this reason. However, as proven by many studies and surveys, most people are actually somewhere in between, if not on a different page altogether. Though the many parties already in existence likely cover the values and opinions of a majority of the population, most of them wouldn’t know because of the way society has conditioned people to think about politics (this includes anyone who is not fully satisfied with any of the major parties, which is a very large demographic).
Though I again ultimately have to disagree with you, I do see your point that many of the people who vote this way today will continue to vote as such regardless. I personally think that a lack of political parties would discourage this, but your theory on the matter is entirely possible as well.
Of course, the chances of the breakdown of the party system in the U.S. are very slim, so this is all hypothetical.
I am personally of the opinion that there will likely be a division within the current Republican party that separates the modern conservatives from the traditional or “true” conservatives, and the first major modern third party will be formed from this division. But again, all hypothetical.
