No one, inside the campaign or out, is assuming that. Everyone...pollsters, run of the mill dems, people inside the campaign, Obama himself...literally everyone recognizes that this will be a tighter race and he won't have as much support as he had in 2008.
This idea about those assumptions is a narrative for the conservative media to attack polls that don't say what they want the polls to say. That's about it. Not a shred of truth or reason to it.

Then explain polls that have Democrats with plus 10 in their polling samples when the final difference in 2008 was plus 7. As I pointed out earlier in Ohio for example the three polls that have Obama slightly ahead use polls where the Democrats match or exceed Democrat participation in 2008. Axelrod , MSNBC and others are basing their prediction of victory on these polls.
I'm not saying they are wrong I was just asking the board if they believe the Democrats will outperform their 2008 performance vice the Republicans (of plus 7). Larry answered in the affirmative (The only one so far) but you and many others seem to be saying no (In which case confidence in an Obama victory should be a little less on this board than it is).

I think I may have tracked down how the Pollsters establish their models. Looking at the Quinnipac poll released today the poll has the President up by 5 in Ohio, 1 in Virginia, and 1 in Florida. I'm sure that will please many on this board, but again it goes back to an assumption for this poll that the Democrats will exceed their performance by 33-50% over 2008. How they meet this assumption is by weighting the responses given party affiliation which tells me what they are reporting is not the actual raw percentage of the responses (ie more people could have actually responded for Romney in these polls but when weighted that dropped the over all percentage reported).
See below

Turns out those explanations were apparently wrong. At least one pollster (Quinnipac) weights its' responses to meet the assumption that the Democrats will outperform their 2008 performance (I suspect all the major pollsters wieght resposnes to meet a model). You in fact are the only one so far in this forum that believes the assumption is valid which is ok and fully supports a prediction of an Obama victory, it also mirrors the Obama campaign belief. However those in this forum that are saying they don't believe those assumptions are correct are the ones whose optimism is a bit baseless.

It doesn't seem that I'm misunderstanding this.
Here is how weighting is explained by PrecisionPolling.com: "It is frequently the case that the people who answered your poll are not fully representative of the region you were polling over. Weighting is a technique to adjust answers to account for over- and under-represented groups."
I'm going to wait to see how Sandy plays out but if everything remains the same by Monday I'll predict easy Romney victories in at least Florida and VA and a close Romney Victory in Ohio. That is based on my belief that Democrats will not come close to matching the turnout advantage they had over Republicans they had in 2008. It would not surprise me if the Republicnas end up with the advantage this time around (plus 2 or 3) and if the latter happens it will be a landslide for Romney..

I know what weighting is.
But virtually every major pollster says that they do not do any weighting at all to adjust for party affiliation. They weigh for demographics but they don't change their results to change the republican/democratic mix that they get from their responses. If they get plus 8 Percent GOP responses, that's what they report. That's because party identification is one of the things that polling is supposed to be measuring - it changes from election to election.
Here's Pew talking about it.

Predicto, do you think they adjust the sampling?
different terms give the same result
both weighed and unweighed have value, but you have to look beyond the surface

Did you not see what I posted from the poll itself?? That is exactly what Quinnipac did. Look at the Florida example again. They show the raw numbers and more Republicans than Democrats were interviewed (352 Rs, 350 Dems) but the poll ended with a 37 to 30 Democratic advantage . This is because they assess that is what the final turnout will be. It is an assumption and pretty sure most polls do this,. Quinnipac could be making the right assumption but is is still an assumption, Rassmussen for example has a different assumption and gives a plus 2 advantage to the Dems (he was interviewed and he mentioned this tonight). The question is who is correct. Gallup weighs their national projection giving the Republicans a plus 1 advantage. Bottomline party affiliation is in facted weighed to fit the model.

Yes, they adjust the sampling. If they reach only 20 percent senior citizens, but the district demographics and history show that 33 percent of the voters will be senior citizens, then they adjust the results to reflect this.
But if they get 40 percent self identified Democrats and 43 percent GOP, they don't adjust based on that. If they did, then what would they be measuring? If more voters are identifying as GOP than last time, that is because the GOP is more popular than last time. That's why people hold elections in the first place.
The idea that polls adjust to add more Democrats or Republicans is a myth.

No it isn't. It is what you think they did.
They adjusted based on demographics, and (in that example) the results changed in favor of the Democrats. In other cases it goes the other way.
Imagine a district that is 50 percent women, but for some reason your phone calls on this poll happened to reach 80 percent men and only 20 percent women. That result would be adjusted - and a side effect would be an increase in the predicted Democratic vote percentage. But it could go the other way the next poll, when you managed to call 80 percent women and only 20 percent men.
Does that make sense?
"The Internet is like a herd of performing elephants with diarrhea: massive, difficult to redirect, awe-inspiring, entertaining, and a source of mind-boggling amounts of excrement when you least expect it" - I wish I had said this.
You are confusing demographics with party ID. This is probably the biggest and most common misunderstanding of polling.
"If a pollster weights by party ID, they are substituting their own judgment as to what the electorate is going to look like. It's not scientific," said Doug Schwartz, the director of the Quinnipiac University Polling Institute, which doesn't weight its surveys by party identification.

if you guys want some opinion on why the polls, many of them are oversampling, over biasing, and over adjusting in favor of D's check out Dick Morris's latest blog
http://www.dickmorris.com/why-the-ny...aign=dmreports
Now, all of this is really speculation, based on the opinions of the people doing 'adjustments' and such We all know how split the country has felt in the last 20 years.
For an astrological look at the election, I give you these two articles. Interesting reads, and only to be taken seriously if you want to.
First is about the election, Mercury turns retrograde on election day.
http://planetwaves.net/astrologynews...ction-day.html
The second is about Obama's and Romney's charts. Warning: in the opening, the author incorrectly names Romney a couple of times, which I think is disrespectful, and the author also gives a disclaimer in the 3rd paragraph.

I don't understand. Are you (and Dick) saying the pollsters are lying, that they claim to not adjust for party affiliation when in fact they are? I get why Dick would claim this, because he's pushing a certain agenda, and because he's, well, a Dick. But seriously, does it make sense that the pollsters who's livelihood depends on accuracy would actually lie, and would deliberately publish results they know will eventually be shown to be inaccurate?
In the end it may turn out that Dick's prediction is closer to the mark then most pollsters. If so, the pollsters will clearly have some adjustments to make to their methodology. But the reason will not be because Dick adjusted for expected party affiliation and they did not (or as he seems to be claiming, did adjust but did so incorrectly).
