1. ANALYSISFour new state polls were released yesterday, three of which moved between columns on the State Chart (see Section 7 below). Oregon moves left today, while Virginia and Iowa each take a step to the right. Colorado stays put in the Lean Obama column. More detail on the new state polls is shown in Section 3 below.
Survey USA was the first to report back in February that the Democratic Party has a chance this year in Virginia, and they were correct. Virginia has become a swing state this year. Survey USA shows Obama trailing McCain by one point in their new poll. We had previously shown Obama leading by a razor thin 0.5 points, so the new poll shows a very small 1.5-point shift to the right.
Survey USA should begin to reassert itself as a leading polling agency starting this month. Like Rasmussen, their polls usually show the race closer in the swing and weak states than it most likely is (in my opinion), and they do release an occasional outlier (sometimes mind-boggling). But FiveThirtyEight.com gives SUSA one of the lowest pollster-introduced error ratings at (+1.02). This is possibly due to the volume of polls they release, but overall they are usually within the ballpark.
Rasmussen shows Oregon as Strong Obama with a 10-point lead, after Survey USA showed Obama’s lead shrinking to +3 late last week. These two polls are averaged, showing Obama leading in Oregon by 6.5 points. Rasmussen also shows Iowa weakening, joining the club in the Midwest of the states which formerly polled Strong Obama.
Our Wigand Electoral Average fell by 2.42 points (see Figures 2b and 5b below) due to Virginia switching sides today.

2. WIDGETS^ FIGURE 2a. This is what we refer to as the “Widget”. In the white section, it shows Obama’s and McCain’s electoral vote projection from three different sources. 270 would be a majority. In the yellow section, it shows three sources of trading and averages for the candidates. The scale for these is 0 to 100, with 50 being a majority. Intrade shows the trading, while RCP-av shows the aggregate average of all the state polls. The Wigand Electoral Average is our own indicator, and shows how the candidates will do if the undecideds nationwide break the same way as the swing states.^ FIGURE 2b. The Wigand Electoral Average is our own indicator, and shows how the candidates will do if the undecideds nationwide break the same way as the swing states. Each of the twelve swing states are listed below the indicator’s current score. The closing figures on Intrade are shown next to each state, with a column to show the change from the previous day. The scale for these is 0 to 100, with 50 being a majority.* * * * * * *

4. DAILY TRACKING – ELECTORAL VOTES^ FIGURE 4a. This graph shows the daily tracking of Obama’s projected electoral votes from three sources. 270 is a majority of the electoral votes. The blue line shows daily tracking from 538.com, which projects what the outcome should be on election day. The red line shows daily tracking from Electoral-Vote.com, which shows a current snapshot of Obama’s electoral progress if the undecideds break evenly. The green line is my own projection, and it shows a current snapshot of Obama’s electoral progress if the undecideds break the same way as the swing states. A trend line is used (dashed green line) to show the average progress since May 19 and possible route for the next seven days.^ FIGURE 4b. This graph shows Obama’s green line and red line from the previous graph, and compares it to John Kerry’s 2004 progress (orange line) as shown from Electoral-Vote.com. (Both the red line and the orange line show data from Electoral-Vote.com)* * * * * * *
5. DAILY TRACKING – WIGAND ELECTORAL AVERAGE^ FIGURE 5a. This graph shows the daily tracking of the swing states total from the Wigand Electoral Average widget above (second chart from the top). To show Obama’s progress in the swing states, divide the latest closing figure by 1200.^ FIGURE 5b. Wigand vs. National Polls, RCP Average and Trading. The Wigand Electoral Average uses both poll averages and trading (swing states), and this graph compares it to the national daily tracking polls from Gallup, Rasmussen and Real Clear Politics (average), as well as the closing trading figures from Intrade (people buying shares with real money) and Rasmussen Markets (people using fake money).* * * * * * *
6. DAILY TRACKING – POPULAR VOTE AND SWING STATES TRADING^ FIGURE 6a. I am projecting 126,750,000 million votes on election day, which is the total 2004 votes plus population growth for each state. A total projected popular vote is calculated for each candidate based on projected votes on election day this year multiplied by each state’s current poll results. This graph shows the daily tracking of the popular vote calculations.^ FIGURE 6b. This graph shows the daily tracking of each swing state’s closing figure on Intrade. The scale is 0 to 100 with 50 being a majority. I commonly refer to the range from 40.00 to 60.00 as “The Zone” because the states in The Zone are true swing states this year.* * * * * * *

Projected Electoral Votes are on a scale of 0 to 538, with 270 being a majority, or projected win. Trading and Averages are on a scale of 0 to 100, with 50.1 being a majority, or projected win.
The Wigand Electoral Average uses public polling results to determine base states for both parties and a short list of swing states, and combines the actual electoral votes from base states with a weighted Intrade calculation for electoral votes from swing states to derive an average on a scale of 0 to 100. On this scale, greater than 50.00 is considered a win for Barack Obama. An average of 50.10 would yield 270 electoral votes, and an average of 100.00 would yield 538 electoral votes.
