MSNBC has posted a matrix of the presidential candidates that compares their views on many issues. You can also go to the candidates' websites and get more in-depth info about where they stand.
Whatever your choice, be informed.
ETA: We interrupt this important post about the presidential candidates to bring you even more important news. Remember the amazing Vogue Knitting patterns that I blogged about here? The ones that they were going to offer for free? Well ladies, THEY. ARE. NOW. AVAILABLE. HERE.
