ElectionProjection.com does a head-to-head analysis using a combination of head-to-head polls, approval ratings and right-track/wrong-track numbers. Is that who you were thinking of?
No, it was a FReeper, but thanks for that site. I checked them out, he has it tied at 269-269 and Kerry with 50.2% of the popular vote. I couldn't see how he got that but when I checked the details, he's about 10 days old with his data and doesn't have the Harris poll and the recent good polls for Bush so that explains it.
He's calling for a Bush win and stated that his low water mark came about a month ago, so I doubt he's biased for Kerry. Realclearpolitics.com is right up to date.
