I guess in the final analysis I think that Obama probably won't do a quckie Arizona stop. This kind of thing just isn't his style. He's a stick-to-the-game-plan type if I've ever seen one.
I did like the thought of it, though. Now that I've said this watch him do it after all...
Late-breaking note: A new poll for Daily Kos shows Arizona 48-47 McCain. Before you say "yeah, Daily Kos," bear in mind that Kos' daily tracking of the national numbers has shown McCain gaining a little ground lately, from 10 or 11 to today's six. So there's absolutely no reason to think the numbers are cooked.
