Most people don't understand what it is or what it means. I refrain from voting when I'm uninformed. I rarely vote for city elections and some random state positions because I don't have time to research the options. That doesn't mean that I or most people don't care about the results, we just don't have the time to learn enough about everything to have a rational opinion on everything.

That's why representative democracies are better than strict democracies. I may not be an expert on everything, but I can usually recognize an expert when I see one.
