It seems to me, through my observations on here, and of the media, that the biggest problem in American politics is the two party system, and I'm curious to know just how it is enshrined in law, is it on the constitution, and what would have to happen to get it revoked?
The two-party isn't enshrined in law; it is a result of plurality voting. Plurality voting naturally lends to the creation of a two-party system. This is called Duverger's Law.
Duverger's law - Wikipedia, the free encyclopedia
In order to change the two-party system, the U.S. would have to change to some other voting system, such as Instant Run-off Voting. In some elections some states have tried to initiate IRV but they were challenged in the courts, and judges have struck them down for violating "One Man, One Vote," a concept that's pretty strong here in the U.S. In IRV, a person gets more than one vote, technically, which is why it gets struck down, but personally I think that's bull****.
One difference between the two-party system of the U.S., however, and the multi-party system of Europe and elsewhere is that in the U.S. there
much less party unity. That is it is more allowable for a member of a party to vote against the platform of the party they belong to.
Take, for instance, the Blue Dogs, the faction of Democrats who are conservatives despite the Democratic Party being the leftist party. The Blue Dogs often vote against the rest of their party.
Another example is the Log Cabin Republicans, a faction in the rightist party that favors advocacy for homosexuals, such as gay marriage and gay adoption, which is generally opposed by the mainstream Republican Party.
This system allows much more "wriggle room" for politicians to personalize their platform in order to benefit their constituents.
