Two-party system

The two party system in America- the Republicans and the Democrats. It's been this way for a while, so what's the problem? Some people claim it causes too many divisions between the people, and, in a way, I agree. Labels like goth, emo, punk, etc. are useless and don't focus on who the person is as an individual. why isn't the same true for what we believe in politically. I think we can stop people from electing incompetent officials if people concentrated on what each individual person believes in without pigeonholing them. If people just check whatever person belongs to their party without really listening, well then, they won't really know what's going on, and that's a voter's responsibility, to choose who is best for the country, not who has the right letter by their name
