I am happy to see your input, but can you put a bit more effort into it than this?
Your statement by itself is just an appeal to authority at this point.
If you are right, can you explain why? And no “look at the polls as a whole” isn’t explaining it, seeing as when I read things like this http://www.nationalpolls.com/stories/2012/0911-examiner-romney.html your post seems… I don’t know, baseless.[/quote]
Beans-
That is a very fair request. If you head over to realpolitics you can get all of the data from this seasons polls. If you look at the majority of the polls (something like 138 in the last year, only a small number go towards Romney). The law of large numbers tells me that any one poll is useless (hope you read that ZEB), but the combined results from all of the polls is really telling. This perspective says that Romney carried less than 20% of the polls. All of them were close, but Obama leads in so many it is hard to ignore.
I might be wrong, but the combined effect of all of those polls going in the same direction gives me enough confidence that you don’t need a chi-square test to see the trend.

Obama’s biggest lead, according to here RealClearPolitics - Election 2012 - General Election: Romney vs. Obama since hitting 4.6 in April, was 4.6 on August 11th.
So they have tied been even since April.
Shit he got a 3.6 point lead after his convention, which is still bascially tied.

How is that basically tied? Over the number of polls the margin of error shrinks…It does not grow. With all of those polls (and the shrinking error term), that 3.6 lead is massive.
Am I missing something with your view of those polls?

Aside from the fact real life doesn’t always follow the polls, I don’t find a sudden spike after a convention after 6 months of basically neck and neck to be massive.
I mean, it has been awhile since my last stat class, but the margin of error is never zero, and a 3.6 point lead 60 days out isn’t some end game figure that couldn’t be well wrong in either direction.
I think you are confusing the 3.6 point lead with a trend that isn’t there. If it was to follow the trend that is there, it will shrink back down to even.

Life does not follow one poll, but it does follow many polls (otherwise, no one would ever poll).
You are correct- your stats teacher did a nice job- the error never hits 0, but it does reduce in size with additional samplings (polls). Just look at the MoE for each poll, larger number of people sampled, smaller error. What do you think happens when you start adding each of the samples–error becomes even smaller- which is why polls typically get about 1000 people or so, MoE hits 3%.
That 3.6% lead is small, but the error is really small and that little romney line rarely gets above the obama line. When it does, it drops back down right quick.
