I will only use polls that use likely voters from this point forward.
Rasmussen Tracking
08/31 - 09/02 ~ 3000 (Likely Voters): McCain 45 Obama 50 = Obama +5
Gallup Tracking
08/30 - 09/01 ~ 2772 (Registered Voters): McCain 42 Obama 50 = Obama +8
(Likely voters are people who vote regularly. Registered voters are just that, registered to vote, a broader category.) “If you look at the six polls up at Real Clear Politics, there is a huge difference between polls looking at likely voters and those that look at registered voters. For likely voters, Obama is ahead by 1.3 percentage points. For registered voters, Obama is ahead by 5 percentage points.” (posted by John Lott on 7-29-08)
