Found a nice site on Presidential Elections and the law. It is Jurist - Presidential Election Law. It provides statutes, cases, news and information about the laws regarding political broadcasting, campaign finance, voter registration and presidential debates. Includes Florida Recount 2000 section. The site notes that it, "presents this Guide as a non-partisan educational resource for voters, citizens, and observers of the US electoral process."
Although it hasn't been updated since 200, it still has lots of good information.
