I think the real problem is the electoral college. It skews the way the candidates campaign. Since most states are an all or nothing proposition, most of the time the presidential candidates barely visit most states. I'm certain the coverage in those states isn't nearly as comprehensive, and consequently, those voters may not be as educated. After all, we, as a nation, are a lazy lot. Most of the time unless the platforms are shoved right in our faces, we don't do the research necessary to make an educated decision.
I'm not sure what the answer is, but there has to be a better way to make the electorate more educated while at the same time making sure each and every vote really does count.
