Election fraud as Bavarian fire drill, or if you prefer, election fraud implemented as a clusterfuck. Of course, we may need United Nations observers to oversee any kind of a real investigation, given the partisan nature of any inquiries into this mess so far. Check out Votescam for interesting things to think about. For the record, I suspect that much of what's there is true, but their aim at the media projections is misdirected. As for their success in tracking down vote fraud in Dade County in that election of a few years ago, I'll merely note that Florida has an international reputation for election fraud, and that the Miami Herald is financing some of the unofficial recounts.
Election rigging in Florida is common knowledge among long-time state residents.
Many of the right-wing sites discussing the probability of election fraud were discussing it in the context of the 'evil' Democrats trying to steal the election for Gore. The amusing irony is that they're still discussing this. The funniest part is that the interesting facts they've uncovered do point at fraud, and when they realize this, I'm expecting a lot of pages at places like Freedom Forum to abruptly disappear. So if you've been inspired by this to do your own investigation, I suggest saving to disk along with a note of the original URL any interesting pages you find and not being surprised if the URLs disappear later. Also note that copies of many pages that no longer exist can be found in the Google cache files.
