To be fair, while we only have 2 parties (with any chance at all) those parties are spectrums. Not everyone within the parties agree with each other. There are wings to each party, and the candidates selected in primaries reflect that. For example, whether you love or hate them, the tea party has almost been a third party in America. Yes they ran as republicans so they'd have a chance, and do agree on a lot of things, there is no question that there are also lots of things mainstream republicans and tea party candidates disagree on. While we stick to the 2 parties, there is a wide spectrum of viewpoints still available within those parties. The republican primary in particular will show that not everyone agrees.
