Are there any democratic countries that don't have a party system for politics?

Where politicians just run on issues and are not identified with a particular party, not supported by a party, not controlled by a party?

If we can’t come up with an example, what do you think about the idea? Could it work? Do you think the party system just leads to the animosity and unwillingness to cooperate in poltics? Is it a necessary evil? Does it promote “us and them” thinking, rather than we are all Americans, or whatever country we choose as an example.
