Dashing Republican Hopes

The right wing's hope in this election is that nearly all the state polls are wrong and they are all wrong in one direction.


As part of their argument they argue that polls were wrong during the heated Wisconsin recall. Actually they were accurate to 1/10 of a percent:



They also argue that the polls missed the Republican wave of 2010. Actually they caught it. What did happen is that right leaning pollsters like Rasmussen and Gallup grossly overestimated the size of the wave:



And, finally they suggest that polls are skewed. That pollsters have a model that they use which pre-assigns what percentage different groups will comprise of the electorate. Most of them don't. Some of the cheap Republican robopollsters do but that's a different story. Most pollsters give the percentages they do because that's what the respondents to the poll are telling them:


"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.

My MIL is a Fox junkie and really has no mind or reasoning of her own. A perfect minion that can be lead and thoughts influenced so incredibly easily. She told my husband on a phone call this morning that Scumney is going to win in a landslide and if Obama wins it will be just barely a win.

My husband works with a tea bagger Rush junkie. He is very happy going into the last days of the campaign, certain scumney will be winning.

I guess if they are only spoon fed propaganda and facts are to be discarded unless they favor them, then I suppose they truly believe this and are happy and optimistic

Oh, their fifth argument is that because Obama isn't doing well among independents he can't win. Well, he's winning in the polls where they got that information from and that is already factored in. Also, a lot of those independents are Tea Baggers who don't consider themselves Republicans. I also see some movement in the polls among independents toward Obama. I suspect that's a function of more latent Republicans masquerading as independents now declaring themselves Republicans. That's why there's not an even bigger shift to Obama in some of the polls. The same people voting against him are still voting against him except a lot of them are calling themselves Republicans and not independents.

It's so difficult to reach the same people that polling did 20 - 30 years ago, the ones nowadays find people I don't believe accurately represent the electorate.

I'm not swayed by them at all, just as I'm not swayed to buy products advertised on television or radio. I buy what I need and I vote regardless.

I stand by my position. I've know several people who haven't been polled even once this election cycle, myself included. If I had, I would have said Obama/Dems, as would these other people. Who are the pollsters polling. Not us! And we vote.

http://www.realclearpolitics.com/epolls/2008/president/national.html


Of course you didn't get polled , polling is based on inferential statistics. One can make an inference from a smaller sample to a larger sample.

Flip a con...If you flip a coin ten times you might get nine heads and one tail. Flip that coin one thousand times and I assure you it will come very close to five hundred heads and five hundred tails. Flip it a million times and I assure you it will be dead even. That's how inferential statistics work.

I don't think anybody expects polls to be accurate to the decimal point.

Because WaPo, ABC, CBS, etc didn't poll the state of North Carolina



If you check the link it contains every published poll for the state from 2/26/08 -11/3/08






You accused me of making a logical fallacy, a straw man without an iota of evidence,


If you care to look you will find myriad peer reviewed studies that demonstrate the efficacy of aggregating polls to predict electoral outcomes.

I thought we were discussing North Carolina polls.


I'm not basing my opinion on Real Clear Politics. I'm basing it on the Law Of Large Numbers. The law of large numbers suggest that as the size of your sample increases your accuracy increases and your findings become more robust. That's why by averaging polls the aggregate of nationals polls came within 3/10 of a percent of the national popular vote in 08:

And within 7/10 of a percent in North Carolina:

Mon Nov 5, 2012, 02:36 AM

Show your debater this article & see if that debater says the same.

History says be skeptical of presidential polls

Excerpts

Back in 1940, the last poll (of adults) on Oct. 31 had President Franklin Roosevelt leading Republican Wendell Willkie by a mere47 percent to 45 percent. FDR wound up winning big, by 54.7 percent to 44.8 percent. A similar phenomenon occurred in 1944, with a Nov. 3 poll putting FDR up by only 48 percent to 47 percent versus Thomas Dewey. FDR again won by a rather handy 53.4 percent to 45.9 percent.

As for elections shifting in the late stages, in 2000, an Oct. 6 poll had George W. Bush at 48 percent and Al Gore at 41 percent, and as late as Oct. 26, Bush was up among likely voters in the Gallup poll by 52 percent to 39 percent. Again, the final vote was Gore 48.4 percent and Bush 47.9 percent.


Watch what I put in bold here.

Most dramatic, on Oct. 27, 1980, Gallup had President Jimmy Carter beating Ronald Reagan by 45 percent to39 percent. Of course, Reagan won by 50.7 percent to 41.0 percent.

And in 1976, the Gallup poll on Oct. 30 had President Gerald Ford at
47 percent and Jimmy Carter at 46 percent. Carter won 50.1 percent to 48.0 percent.


People put WAAAAY too much faith in polls as if they're all-knowing.
Check out the last line from article author Raymond J. Keating for extra marshmallowy goodness.

The big lesson? Don’t be surprised if things diverge, perhaps quite markedly, on Election Day compared to what even the most recent polls communicate, never mind polls taken a month away from when people actually cast their ballots.

I already said you are right twice now. That's a compliment. Let me say that again. That's a compliment. And I'll say my title again. I don't take challenges personal.

However, the RCP compilation is a straw man and it proves the point that taken individually, the polling was mostly garbage and I'll bet there were a ton more taken in 2008 by less reputable pollsters that showed NC even farther from the mean than this neatly packaged list.

You win. I give up. I'm undeterred.

It's so difficult to reach the same people that polling did 20 - 30 years ago, the ones nowadays find people I don't believe accurately represent the electorate.

Mon Nov 5, 2012, 01:49 AM

But the Law Of Large Numbers suggests that by averaging all the polls you can come up with a rough approximation of the universe you are attempting to measure. And by rough I mean a reasonable degree of accuracy...Something much lower than five to ten percent which render a poll useless...


http://en.wikipedia.org/wiki/Law_of_large_numbers


We are discussing math. Nothing more...Nothing less...


And there might come a point where traditional polling is overwhelmed by response rate problems and polling is demonstrated to be inaccurate. We aren't at that point yet. Since you made that point at the beginning of our tet a tet it's incumbent upon you to prove it.

I'll wait for the proof.
