With the addition of Saturday polling data to the 3-day rolling averages used by the four daily tracking polls, Barack Obama has widened his lead over John McCain for the third day in a row. Here's what it looks like:
Obama's lead in the tracking poll average is now 6.5 points. For a week, up until September 25, Obama led by about 3.5 points. Interestingly, the tracking polls released Sept. 26 were the first to include data from after McCain's announcement he was suspending his campaign and after people watched the Palin-Couric interview.
The trend against McCain may just be continuing or it may have accelerated after Friday night's debate. The R2K poll for DKos shows that in Saturday's sample, Obama by 9 points, 51 to 42. We'll see tomorrow if 6.5 is the new plateau or if the lead edges higher.
