If you talk to random people in a democracy, they can't vote their interest even if they wanted to, because they don't know what's actually affected by politics and what isn't.
Some people switched to culture/values voting (ie, telling other people what to do), some people just enjoy winning and so vote for whoever they think is going to win.
