(CNSNews.com) – Democratic presidential candidate Barack Obama leads Republican presidential candidate John McCain by eight points - 50 percent to 42 percent – according to the latest Gallup poll released Thursday.
Obama has averaged a nine-point lead since Oct. 1. In the traditional model, defining likely voters based on current voting intention and past voting behavior, Obama holds a 50 percent to 42 percent lead or eight points.
In the expanded model, which considers only current voting intentions, Obama’s lead is 51 percent to 44 percent or seven points.
The poll was conducted Oct. 27-29 from a sample of 2,800 registered voters and has a margin of error of plus or minus two percentage points.

Meanwhile, a Real Clear Politics Poll average shows Obama is six points ahead of McCain.
In eight key states, which have voted for President Bush in the last election, Obama is leading McCain. Obama has a three-point advantage in Florida, two-point advantage in North Carolina, five points in Ohio, six points in Colorado and Virginia, and Nevada and New Mexico. And in Missouri, Obama has a slim lead of 0.2 points.
Obama also leads by nine points in Pennsylvania.  
Meanwhile, McCain is leading Obama by one point in Indiana, three points in Montana, four points in Georgia, five points in his home state of Arizona, and eight points in West Virginia.
