Primary Day Dilemma

This morning I woke up confused. It's Primary Day, and although I have detached myself from either left or right parties -- I'm lost about who to vote for. When you think about the candidate you're choosing, do you base it on what you hear from mainstream media? Or do you mostly base your decision upon what other people say about them? How do you know who's right and who's wrong? And how do you get real and true info on each candidate? Do you believe what they say? I mean, let's face it -- all politicians are liars anyway. Here's my dilemma. Not every pro-lifer is a republican. Not every person of the LGBT community is a liberal or democrat. Not every Christian is a republican either. Why do all of these political opinions categorize someone into a political party? I guess you can call someone an "independent" if they have various views on certain issues? Or maybe that's up to the person? Or, maybe the democrats and republicans all sleep in...
