Oh Gallup, what is wrong now?


House

Just a week ago, the big story from Gallup was that the Republicans had hit an all-time high lead in their poll. I covered it despite questioning the poll in the past. Everyone covered it.

But now, suddenly, in the Gallup poll the race is even? How can that be, and what does it mean?

Of course, last week saw more than the Republicans taking a 51-41 lead in the Gallup generic ballot. The party also took the largest lead of the year in voter enthusiasm: 50-25, with independents at 28. In depth: Republicans favored their own 96-3, Democrats favored their own 88-9, and Independents favored Republicans 48-31.

What’s changed? Democrats have swung nine points to favor their own party 93-5. Independents have swing a point to favor Republicans 49-33. Republicans swing 5 points to favor their own 93-5. Somehow, all three of these add up to a ten point total swing. Further, voter enthusiasm remained unchanged among all three groups, but decreased overall by one point.

There’s only one conclusion to draw here: this week’s Gallup captured a lot more Democrats than last week’s did. That’s the only way these numbers can add up. So unless we actually think that the electorate is actually beginning to identify more with the Democrats than with the Republicans, this is what we call an outlier: one of those one-in-twenty of worse events where the poll just isn’t even close to the actual results, and isn’t reflective of reality.

How they managed to get an outlier rolling up a week’s worth of daily tracking though is beyond me.

How many times did they have to take their polls to get the results to look this good for the Ds?

…What I said in response to the other Gallup diary:

And that is – Gallup’s week-to-week numbers are [dung].

If you look over the past four weeks of Gallup results, the GOP lead was +7, +3, +10, and +0. If you average those four results, you end up with a GOP +5 margin, which sounds about right for a Registered Voter poll (and would likely translate into at least a GOP +10 margin in a Likely Voter poll – see recent Rasmussen and ABC/WP results).

So, when it comes to Gallup, I’ve been tending to ignore the week-to-week results, and paying more attention to the four-week average.

All that said, I have no doubt that you are correct in the ‘micro’ analysis of Gallup’s most recent poll result.

Which is just another way of saying that – we’re both right:
Gallup’s week-to-week numbers are [dung]. ;)

 

Hmm

Using NOAA and IPCC Computation Methods

Maybe they got their charts and graphs mixed up and began using the global warming crowd math.

 

That's it for me

As you’ve been telling us for weeks, Gallup’s polling has been up and down and inconsistent from week to week. If this gets backed up by Rasmussen, then I’ll reconsider their polling methods and results. Otherwise, I’m through with them. No reputable polling firm would put out results in such conflict with polling done only a week earlier.

The key word here is "reputable." I wonder how

much pressure they got from dems to change this. All I know is that dems, lead by blowhard Chris Matthews was touting this poll as the beginning of a comeback.

Yeah, and this poll blends in well with Obama's

Three other polls do not agree with Gallup

Coop Wednesday, September 8th at 8:36PM EST (link)

-Gallup yesterday, both parties tied 46-46
-Democracy Corps today, GOP leads 49-41
-Wash Post yesterday, GOP leads 53-40
-Rasmussen 9/6, GOP leads 48-36

Their reputation has been going downhill,

but with this latest chapter, I dare say it has gone into the toilet.

 

The Three Polls You Cite Are *Likely* Voter Polls

IJB Wednesday, September 8th at 9:04PM EST (link)

Gallup is (so far, still) a REGISTERED voter poll.

That accounts for some of the difference. Like I said – if you look at the 4-week average, Gallup’s results are actually in line with the other 3 polls, when you account for Registered vs. Likely voter polling result differences.

The problem is their week-to-week volatility is rendering them pretty useless.

Hopefully when Gallup goes to the ‘Likely Voter’ screen, their volatility will go down…

 
 
 

The Volatility Speaks Volumes

It really diminishes the credibility of Gallup on this particular polling issue.

Someone else (I forget who said it) has mentioned in the past that Gallup’s accuracy in poling the “generic ballot” leaves a lot to be desired. Now I understand what they mean.

 

Maybe the country is just strating to pay attention

maybe the country is finally starting to pay attention!

If the "Country" were starting to pay attention...

JadedByPolitics (Diary) Wednesday, September 8th at 8:52PM EST (link)

the Republicans would have a 20 point lead on the Socialists!

Judges from the last Olympics–no the World Cup referee is on going the math at Gallup.

Its like the weather in Memphis–don’t like this week’s gallup numbers–wait a week and the GOP will be ahead.

 

As a cross-over

Sundayjack (Diary) Wednesday, September 8th at 9:54PM EST (link)

In his piece of a week ago, Jim Geraghty’s deep-throat, Obi-Wan, mentioned that a poll showing things closing up would come out soon in order to change the narrative. Happened quicker than even he probably expected. The problem is, though, when a guy like Chuck Todd – a Tom Harkin Democrat – warns people against using Gallup, this sort of trickeration might blow away in the breeze.

“Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies.”

 

Apparently...

…Olberdork and Thrillupmyleg were gushing about this outlier poll as a “signal” of the Dems’ revival.

Skewed by Labor Day?

indylawyer (Diary) Thursday, September 9th at 12:17AM EST (link)

Gallup’s polls do tend to gallup around quite a bit. But I wonder whether the long Labor Day weekend also skewed this poll a bit. Lots of married couples with kids getting a last long weekend out of town means lots of Republicans not answering their phones.

It certainly wouldn't be the first time it happened

Adjoran (Diary) Thursday, September 9th at 6:14AM EST (link)

But I doubt that alone can account for the difference.

Neil’s “outlier” theory is probably correct – they got a bad sample, perhaps in part to the holiday effect suppressing the GOP, or just bad luck. Like the old computer guys used to say, “Garbage in, garbage out.”

Let’s see what they come out with next week before we hang them all.

 
 

You Guys Are ALL Wrong On This

Michael Dugas (Diary) Thursday, September 9th at 8:58AM EST (link)

You see the deal is that about 8 weeks ago a member of Gallups team dropped his mocha cappuccino double sweet with soy all over their Magic 8 Ball and broke it. And Linda, who used to do the tea leaves before they acquired the Magic 8 ball, is in Gaza acting as a human shield and can’t get away right now to do her tea leave deal.
So Gallup has actually had to attempt to do the math for real. Obviously it’s been a long time since they have had to do that “old school” math thingy.
