Whoops
Props to New Republic's Jon Chait for spotting this one: Cheney mistakenly pointed viewers to FactCheck.com rather than Annenberg's FactCheck.org. The former is a pointer to George Soros' website.
Update: Commenters say the redirect was actually put in place very quickly after the debates. Must've been very quickly indeed, as I checked it not too long after. Also, my own whoops: I initially misattributed the catch; it's right now.
