Tracking Poll Update: 7’s are Wild

Not only does Barack Obama continue to have a lead of around seven percentage points,  but there are now seven trackers included in our composite.  The latest tracker comes from ABC/The Washington Post, which started reporting a three-day average on Monday.

Date	Gallup	Rasmussen	Hotline	Research 2000	Zogby	IBD/TIPP	ABC	7-Poll Adjusted Average
10/20	9	4	5	8	6	6	9	6.7
10/21	10	4	6	8	8	6	9	7.2
10/22	8	6	5	10	10	4	11	7.6
10/23	6	7	5	10	12	1	11	7.3

It’s important to note how unstable Zogby and IBD/TIPP have been recently. Wild swings in only one or two of the trackers (especially in opposite directions) is concerning. In addition, take a look at the following TIPP cross tab:

Age 18-24: McCain 74%-Obama 22%. Yeah, I know that some hippsters are voting for McCain to be ironic, but this is over the top. Even a subgroup from this age group shouldn’t have a margin of error large enough to explain this.  Nate Silver believes that they must be under sampling young voters by a very tight likely voter screen. Either that, or they realized everyone would be talking about them if they reported a result like this (damnit all!) Nonetheless, they’ve secured a spot on The Drudge Report’s front page for the last two days (Zogby had been there before).

With all that said, we’ve decided to keep TIPP/IBD and Zogby in the composite. With seven trackers, their swings are largely mitigated. However, we are considering a slightly different methodology to deal with some of these issues. We’ll have more on that this weekend.

Tracking Poll Update: Obama +7

Election Day is exactly two weeks away, and Senator Obama has a solid seven point advantage in the composite of the tracking polls. The mainstream media is trying desperately to push a “McCain surge” narrative (close race = ratings). However, the raw numbers don’t show much of a narrowing at all. In fact, the race looks very stable between Obama +6 and Obama +7 over the past week to ten days. Yes, that’s off Obama’s high of +8-9 points of two weeks ago, but a solid lead nonetheless.

Date	Gallup	Rasmussen	Hotline	Research 2000	Zogby	IBD/TIPP	6-Poll Adjusted Average
10/13	10	5	6	12	4	2	6.7
10/14	9	5	6	11	6	3	6.7
10/15	7	5	8	11	4	3	6.3

10/20	9	4	5	8	6	6	6.4
10/21	10	4	6	8	8	6	7.0

Tracking Poll Update: Obama +6

With only 16 days left until Election Day, Senator Obama has a 6 percentage point lead over Senator McCain in the composite of today’s tracking polls. If you include only the original four trackers (Gallup, Rasmussen, Research 2000, and Hotline), Obama’s lead is 6.7 percentage points. Overall, the race seems to be relatively stable. Today’s numbers are important in that they are the first to include only interviews after the last presidential debate.

Date	Gallup	Rasmussen	Hotline	Research 2000	Zogby	IBD/TIPP	6-Poll Adjusted Average
10/13	10	5	6	12	4	2	6.7
10/14	9	5	6	11	6	3	6.7

Tracking Poll Movement?

We’ve decided to include two additional trackers–Zogby and IBD/TIPP– in our new methodology, for a total of six trackers.  Our new methodology weights by the number of respondents in each poll (inverse of the square root of the sample size). Therefore, Rasmussen and Gallup (which survey about three times as many people as the other trackers) have a weight of 1.7 and all other polls have a weight of 1.0.

Here is a look at the past six days for all six trackers:

Date	Gallup*	Rasmussen	Hotline	Research 2000	Zogby	IBD/TIPP	6-Poll Adjusted Average
10/13	10	5	6	12	4	2	6.7
10/14	9	5	6	11	6	3	6.7
10/15	7	5	8	11	4	3	6.3
10/16	6	4	8	11	5	4	6.1
10/17	6	4	10	10	5	5	6.4
10/18	4	5	7	7	4	7	5.4

Here are the trends for the month prior to this past week:

As you can see, Obama’s rise in the polls appears to have peaked about a week ago at an advantage or 8 or 9 percentage points. This makes sense as this was likely his ceiling of support (54 or 55% of the vote in a two-person race). This weekend (with a little over two weeks left), it appears that Obama is now ahead by 5 or 6 percentage points. I believe that we may now be in the middle of a regression to the mean of Obama +4 or 5 percentage points, which is where the long-term equilibrium for this race was for most of the summer. Therefore, in a way, the more things change, the more they stay the same…

*Gallup has switched to reporting likely voters in the past week, so their trends are not as straightforward as they may appear*

Tracking Poll Update: One Month Out, Obama +8.25

With exactly one month left until the November 4 presidential election, all trends continue to favor Senator Obama. For the first time today, Obama is up by more than eight percentage points in the composite of the trackers. Even the adjusted average, excluding the two outliers, still shows Obama up by seven and a half percentage points. It is clear that if the election were today, it would be close to a landslide. But of course, there is a month left, and anything can happen in a month. Hence, the McCain/Palin campaign will go completely negative for the last month of the campaign. They have no other choice.

Here’s a look at today’s numbers and recent trends:

Tracking Poll Update: Pre-VP Debate Equilibrium?

Just in time for tonight’s VP debate, we appear to once again have stability in the tracking polls. Today, for the fifth straight day, Obama’s lead in the tracking poll composite is between six and seven percentage points:

9/28: O+6.5

9/29: O+6.75

9/30: O+7

10/1: O+6.25

10/2: O+7

This comes almost immediately following a period (before the first presidential debate) where Obama held a lead of between four and five percentage points for eight consecutive days.

Here’s a look at today’s numbers and the trends:

Tracking Poll Update: Obama +7

Today’s tracking polls are important in that they are the first tracking polls to include only interviews conducted after the first debate on Friday.

9/30:

Gallup Daily: O+6
Rasmussen: O+6
Diageo/Hotline: O+6
Research 2000: O+10

Simple Average– O+7
Adjusted Average– O+6

Notice that today, for the first time, three out of the four tracking polls have exactly the same Obama advantage of +6, and therefore the adjusted average (excluding outlier trackers) of Obama +6 is a full percentage point different from the simple average of Obama +7. However, regardless of whether Obama’s lead is 6 or 7, trends have been moving wildly in his favor recently:

9/25: O+3.25

9/26: O+5

9/27: O+5.5

9/28: O+6.5

9/29: O+6.75

9/30: O+7

It is unclear how much of this movement is the result of the first debate, McCain suspending his campaign, and/or the crash of the financial markets. My guess is that the latter is having the most effect, but the other two factors are indeed interacting with this to create such a precipitous decline for Senator McCain.

In fact, for the first time, Pollster.com’s regressions shows a statistically significant 5 percent point lead for Obama with 95% confidence.

Here’s a look at the trends:

Tracking Poll Update: Obama +6.5

The first daily trackers with a significant number of interviews from after the first presidential debate came out today. The composite of these trackers continues to show movement toward Obama over the last several days.

Let’s take a look at the last four days:

9/25: O+3.25

9/26: O+5

9/27: O+5.5

9/28: O+6.5

The trackers released September 26 were the first composite in 9 days NOT to show the race between Obama +3 and Obama +4. Thus, it is important to note that this most recent swing towards Obama appears to have started before the first presidential debate, but after McCain announced he would “suspend his campaign.” The question remains about how much these two effects will interact. We’ll have to wait until Tuesday, when all trackers will only include interviews from after the first debate, to get a clearer picture.

Tracking Poll Update: Obama +5

For the first time in nine days, the tracking poll average has deviated outside of the Obama +3-4 percentage point window, with Obama taking a +5 composite advantage. Not only is Obama polling well in the two new trackers, but also in the two traditional trackers. In fact, Rasmussen, which has always been the least likely to show swings toward either candidate because of their tight weighting methods, is now showing a five point Obama lead.  Today’s trackers will be the last numbers released that include only interviews from before tonight’s debate. Therefore, when looked at in combination with the numbers of the past week, these numbers should give us a good benchmark to assess the effect, if any, of the debates on polling.

Here’s a look at today’s numbers and the trends:

9/26:

Gallup Daily: O+3

Tracking Poll Update: Race Stable at Obama+3 to 4

I think it’s officially safe to say that for the first time since mid-August we have a stable race. The average of the four trackers has not deviated by more than .75 percentage points over the past five days. This is very remarkable:

9/18: O+3.5

9/19: O+3.25

9/20: O+4

9/21: O+3.25

9/22: O+4

9/23: O+3.25

Pollster.com backs up this simple averaging with their own regression line that shows Obama up by 3 percentage points nationally. Notice how you can make out the Obama convention bump, the McCain convention bounce, and the most recent Obama surge.

Of course, I’m sure this temporary inertia will shift somewhat after the first presidential debate this Friday. However, if you’re in the Obama camp, you’ve got to like these numbers.

Here’s a look at today’s numbers and the trends:

9/23:
