A few problems with the
article ideas mentioned in the article:
The increasing use of cellphones is a problem that pollsters are eventually going to have to deal with. I don't have a landline, and I vote. But they did fine in 2004 without them, and it may be a gradual shift toward this being a significant problem.
They did choose the most egregious examples, and early voting makes their California example somewhat mis-placed. The polls in the Dem primary weren't really all that bad...for a primary.
All in all though, some very good points. I agree with the article's conclusion that the Bradley Effect is far from a certain thing.
Thanks for posting it
