I tend to agree with you, although I'll reserve that opinion until I hear Vorlon's view of it.
Just wanted to pop in again here, because apparently (it was mentioned on the MI poll thread) Vorlon (I presume he's your resident poll expert? I've not been around here long enough), has confirmed my statement (not personally said I was right... but he has stated something similar... I didn't see such a post by Vorlon, but someone was referencing him)...
The challenger gets a vast majority of the votes.
Though I admit it's a very questionable thing to do due to methodologies, I can also tell you that if you take the six most recent national polls and average the three with the largest pool of undecideds versus the three with the smallest pool of undecideds you'll see that, indeed, the undecideds break better than 2:1 for Kerry. I'll admit it's a bit shady to be averaging polls like that, but it does indicate that the 2:1 rule does hold.
I mention this because a lot of Bush supporters on this thread and the MI poll thread are disregarding this "rule", for a number of reasons. I'm not being pro-Kerry here (I don't have much of an axe to grind, I don't like either one), I'm just being realistic. The Dems appear correct in flaunting this axiom around. The "resident expert" has confirmed this, and current poll averages IMPLY the same (though, again, I'll say that poll averaging like that is a bit shady).
So, with about 5-8% undecided in most states (more in some), Bush needs to be about 2-4% in the lead for it to really even be a dead heat. If I could figure out how to post my prediction here (I'm a bit of a techno-idiot), I would. It's straight from the poll numbers, but using the 2:1 interpretation and tipping any ties to Kerry, due to the trends plus the Nader factor (some Naderites will likely go for Kerry at the last minute). You'd see that it's far more Kerry-colored than a map using the poll numbers straight-up, with no interpretation.
Anyway, sorry for being so long-winded... I don't post often, so needed to get all my thoughts out at once! :-) Just wanted to chime in again that there is some validation on the 2:1 (or more!) issue I raised earlier.
