There's a subject that I've been purposefully avoiding. Vote fraud. Sukabi and Michael H. from Spontaneous Arising have been pushing and gently prodding, but I'm still keeping a lid on it. ;-)
Curious? Use the web to your advantage - follow the links from Michael's site. There are two articles in particular that are, ehhh, thought provoking to say the least: here and here. And the links in those articles will lead you elsewhere.
Above all, remember this: a guy like John Zogby doesn't stake his professional reputation and future on a whim, chance, rumor, and conspiracy theories.
Shhhhhhhhhhh.
