The Last Time I Saw Harris

The latest Harris Poll gives us two choices for potential likely voters, with greatly varying leads (2% and 8%) for Bush. Apparently, they're not sure if they should measure likely voters in a new or traditional mode.

This won't do. Any pollster (heck, any person) can give you a bunch of different results based on different methods saying one of them is probably correct. The Harris Poll is a venerable institution, but if they can't tell us what they actually think is the best data, then who needs 'em?
