CNN's story "Online dirty tricks may mar U.S. elections" Paints a pretty clear picture of what is coming in the final days of campaign 2008. They detail a litany of voter tampering and intimidation tactics but interestingly they don't make any judgement about where those tactics originated.
Virtually all of the issues discussed in the article were attempts by the GOP or it's operatives to disenfranchise Democratic voters in swing states. Make no mistake. The GOP doesn't want you to vote unless you are a middle class white male who is a registered Republican. They will do anything to make sure that others will not vote. Keep that in mind when you read about how your name has been purged from the voter rolls and you cannot vote in the national elections.
The GOP or it's operatives will lie and cheat in any way they can to win. The old boys network is all up to speed and in full effect; ready to drop the voter suppression on an unsuspecting public.
