Roger, if you go to this website, it will give you the difference in electorial vs. popular since they've been counting popular votes.

According to this, there are only 4 elections that would have turned out differently. However, I DO believe that there are a lot of people that may not even vote because of they feel like.. "what's the point, I live in a Blue state or I live in a Red state. If I vote the opposite, it isn't going to matter anyway." I think if you got rid of the electorial college and we had a system where every vote really does count, you may have more people come out of the woodwork on BOTH sides and get their butts to the polls.
