This consultant feels differently than Zogby and some others.
It probably depends on what issue is foremost on the voters' minds. If it is the economy, corporate scandals, state budget deficits, etc., I would tend to go along with the anti-incumbent sentiment. If it is the war on terrorism, national security, Iraq, etc., I would say that would favor incumbents. Not surprisingly, the Dem-leaning consultants think it will be the former, while the GOP-leaning consultants think it will be the latter. :)
BTW, I do have WA-3 on my list of long-shot races. I'm not seriously expecting it to be competitive, but it's one of those that could conceivably become competitive in the right circumstances (e.g. massive anti-incumbent wave, etc.). Bush won this district 48-46 over Gore.
