Ignore the 2% Figure . . .

Your Republican friends will tout a Gallup poll saying the margin is down to 2%. Toss that out the window based on the following:

Gallup is presenting two likely voter estimates to see how preferences might vary under different turnout scenarios. The "expanded" model determines likely voters based only on current voting intentions. This estimate would take into account higher turnout among groups of voters traditionally less likely to vote, such as young adults and minorities. That model has generally produced results that closely match the registered voter figures, but with a lower undecided percentage, and show Obama up by six percentage points today, 51% to 45%.

The "traditional" likely voter model, which Gallup has employed for past elections, factors in prior voting behavior as well as current voting intention. This has generally shown a closer contest, reflecting the fact that Republicans have typically been more likely to vote than Democrats in previous elections. Today's results show Obama with a two-point advantage over McCain using this likely voter model, 49% to 47%, this is within the poll's margin of error. -- Frank Newport
