Problems with the 10/2 Newsweek Poll I see several problems with the Newsweek poll.
#1. It was conducted almost entirely on Friday and Saturday morning. It didn't poll the Eastern and Central time zones on Thursday night. Weekend polls like this usually undersample Republicans.
#2. It has more Democrats than Republicans. I am not certain about the over-under sampling of partisans. I tend to think if the poll is properly conducted, you need to look at party ID as a dependent variable, one that changes with ups and downs. Now -- are we to believe that in the last month there has been more than a 8% net switch in partisan identification? That is what the Newsweek poll from 10/2 stacks up with the Newsweek poll of 9/10.
#3. It is not problematic to me that it is 52% women and 48% men. What I find problematic is that the *men* who were surveyed support Kerry 47% to 45%. Not even Bob Dole did this poorly in 1996. This indicates that they undersampled Republican men. This would, incidentally, make sense in light of the fact that almost all of the sample was done on Friday. What are large swaths of Republican men doing on Friday nights in those red states in the fall? A. During the day they are working; B. During the evening they are at HIGH SCHOOL FOOTBALL GAMES!
(This, my friends, is the reason Kerry is in the lead. He has an insignificant lead among women and Independents...but he also has a similar lead among men. This is unheard of.)
Newsweek usually rushes polls out. I think they do it not so much to get a sense of the electorate, but to make news. Rember that Newsweek is the only poll with the honor of: A. Showing Bob Dole down by 2% in 1996. B. Showing Walter Mondale beating Reagan in 1984. It is not because they are biased, but because they rush their polls out. The people who are sitting at home on Friday day and Friday evening are not a representative sample of the general American population.
All polls need to be filtered by common sense. This Newsweek poll is like that Pew polls from September. The first showed Bush up by >10, the second showed Bush up by 1, the third showed Bush up by >5. Now, do we really, honestly, truly think that the electorate has bounced around so much?
Similarly, with this Newsweek poll. Do we really, honestly, truly think that Bush is losing men and almost tying women? Do we really, honestly, truly think that the dynamic of the race has shifted by *eight points* since September 10? If so, I have a bridge I'd like to sell ya! :-)

Ok...maybe I was a tad hyperbolic Even though I maintain Bush won the debate, I think I was a tad hyperbolic about a negative bump for Kerry in the polls. I expect him to get a small bounce, but this is not because he won the debate. Again, I maintain he did not win it in the true sense.
Kerry will probably get some points for those Democrats who were in the undecided column (i.e. the depressed Democrats) IF (and only IF) the polls like Gallup and Pew are right, those polls which show Kerry at about 40%. Polls which show a higher Kerry output going into the debate, around 46% will show a smaller bump.
Update: Greenberg, Quinlan and Associates show Kerry netted two points on Bush. So there ya go. I generally eschew partisan polls (they are released to influence the news, not to report it). I think this poll is methodologically sloppy, as it measured people before and after the debate (Therefore by contracting those respondents for a post-debate conversation, this poll inclined those people to pay attention more than the average voter would. This makes the sample size unrepresentative of the population in a relevant way.)
Nevertheless, there is no reason for the Dems to jump for joy over this poll. For several reasons: 1. Bush improved his standings across the board, too (though he did not do so as much as Kerry did). 2. Kerry's gains on personal qualities were outside the margin of error, but his bump in the polls was not. 3. Bush still leads Kerry on all the questions of Friday's debate. Iraq, terrorism, etc. Kerry did close the gap. As these numbers occurred on the day of the debate, they will probably deflate -- and return the race to the equilibrium that has existed on these internal issues for a month. 4. The pre-debate horse-race number (Bush 50, Kerry 46) is a tad small. 5. This poll over-sampled third-party voters by at least four points. Three percent of the respondents plan to vote for Nader. Two percent plan to vote for "somebody else." That is 4% more people there than who are showing up in other polls. I would be curious to know if the 2%who switched to Kerry were people from this 5% group.
