I would suggest examining your priorities. What is most important to YOU? For example, I am concerned with how much money the government takes from me and how they spend it more so than gay marriage or global warming. Examine your life, truly look at how you live and what you think the government's role should be (or shouldn't be) in your life. Don't let them (i.e. the candidates, the media, the Super PACs, the late night comedians) tell you what should be important to you. Don't let them intimidate you! Decide what a couple of the big issues are to you and your family, then investigate the candidate's positions on those few points. Hopefully, this will help avoid becoming overwhelmed.
