Sam, Mason Dixon disappointed me in VA this year. Seems like SUSA and Roanoke were the most accurate of the 2005 season.
Virginia does not equal Florida, especially not for M-D. Besides, there's ages of experience we can talk about here.
It is rather ironic that in 2004 only one poll came in over Bush's final margin in Virginia, the rather unknown Times-Dispatch poll. Then in 2005, only one poll came in over Kaine's final margin in Virginia, the totally unknown Roanoke poll. Maybe this explains Virginia (probably not).
I'm fine with SUSA, although they didn't do particularly well in Florida in 2004, but if you want to put faith in a college poll I'd never heard of before this race, be my guest.
