Be informed! Since it is an election year, people like Pink Slip will twist the truth and present it as fact, in order to score political points. Because it seems worse than ever before, be sure you are informed and check http://factcheck.org to see who is twisting the truth. You can also search the Internet and find other sources too. It is important to be informed in your choices and that includes having good information.
Remember, factcheck does not vet voting histories, they look at advertisements and allegations and see if they have any merits. You can still love or hate the real votes or positions and like Fred suggested below http://opensecrets.org .
