Some good and bad movement for both candidates today, but the biggest pro-Obama movement comes in the model where McCain was closest.

Perhaps the past couple days were just a momentary blip? Because it doesn’t look like McCain has been able to keep any sort of advantage he gained.

Registered Voters: Obama +8

Likely Voters (Expanded Model): Obama +7

Likely Voters (Traditional Model): Obama +5

Gallup talks history and expectations…

Both likely voter models currently show a slightly closer race than is evident in the registered voter estimate. Obama has never trailed in either likely voter model since Gallup began tracking likely voter preferences in early October, averaging a four-point lead using the traditional model and an eight-point lead using the expanded model.

Just five days remain until Election Day, and McCain and the Republicans are campaigning hard in key states to try and change Obama’s lead. Late comebacks are rare, but have occurred, including Harry Truman in 1948 and Ronald Reagan in 1980.

More tomorrow…
