I understand the original purpose of political parties was for people who share the same views and beliefs to get together and get someone who shares those views into office. However, it simply doesn't work like that. People are so biased towards their party that they vote for whoever is affiliated with their party, no matter how bad they may be, or how much of a slime-ball they are, or how simply unintelligent they are.
The only thing political parties are doing is tearing the country apart at the seams. People get so bent out of shape about things, that a lot of people (read: a lot, not all) throw insults and tell someone from another party how stupid they are without even actually listening to what's being said.
When it comes down to it, people are forgetting what the main purpose should be at the end of the day; helping the country improve. Not helping the Democrats, or Republicans, or any other party, but the country and its people as a whole. That's what is lost in all of this turmoil, and it's very distressing.
