I suppose you're reference to the shrinking 28 is relative to voter turnout?
Hmmmmmmm. I wonder how many are out there who think like Joe, but didn't get to the polls because they didn't really like McCain either? Impartial because they view both relevant candidates as front or back view of the same entity. You're a partisan guy Bear. Very black/white, left/right, right/wrong. Humans exist in (at least) three dimensions.
Actually I am not all that black/white, my profession just doesn't allow it. I would be out of work within days. But when I make a decision based on the facts that I have, I don't waiver from it. Don't confuse those two very different traits.
The Shrinking28 references the poll numbers for Bush the last few years. I noticed a trend that, no matter what the subject, and no matter how crappy the problem all the major polls would show, during the darkest hours for Bush an approval rating of 28%. I mentioned it here and on another board back in 2007. As time went on the number started jelling to 28% when things got bad. And when Bush left office the final approval rating was 28%. It shrank down from the 70s after 9/11 and the high 40s in 2003.
So my conclusion was there there is a subset of people who, no matter if Bush was greeting Girl Scouts in the Oval Office, bombing hospitals, pardoning turkeys or raping goats on the South Lawn would tell pollsters that they APPROVE of Bush. And that number would be 28%.
