If your aim is to vote responsibly, then the news is a poor place to get information to help you decide. Not just because of the obvious political biases, but choice of stories they lead you to believe are important. Sex scandals, he-said-she-saids, or some crime that gets all the attention for weeks while numerous other similar crimes are ignored. A lot of really unimportant gossip magazine type stories that have little to do with reality other than being cherry-picked from it. The news does a poor job of reporting honestly on dry boring information that has significant impact. Instead, it picks stories that it presents as important but in fact are chosen because they're engaging. An obvious example is the over-reporting of terrorism compared to car accidents. People vote on terrorism because the TV told them it's important and didn't say much about something boring like bad marriages or poor risk evaluation skills that silently ruin people's lives on a massive scale.
You can use Wikipedia instead. Look up wars, statistics about crime, cost of living, a law that you've been affected by, or whatever is important to you, as decided by you, not pushed into your head by the news. There are enough people voting according to what the TV told them is important that you're not really making things better by adding yourself to their ranks.
