It's a label trying to simplify a large group of complex people with complex political opinions. I personally like ideas from both parties on different topics, and my preferences change over time. The whole concept of a group of independently thinking and informed people liking all or nearly all of what a particular political party of two choices stands for is illogical (and probably statistically impossible). Many people vote against a party rather than for because of the barrage of negativity each party pushes out against the other. That's why attack ads are both prevalent and distasteful: they work.
