Gallup Daily: Steady as she goes.

Gallup Daily Tracker is out. Here are their three scenarios:

Registered Voters
Obama 52
McCain 42

The numbers were 51-42 yesterday, so Obama's number goes up one while McCain remains even with where he was yesterday.

Expanded Likely Voter Model (Intent)
Obama 53
McCain 43

The numbers were 52-43 yesterday, so Obama actually improves one point on this metric as well.

Traditional Likely Voter Model (Intent and past behavior)
Obama 50
McCain 45

The numbers were 50-45 yesterday; in fact, these numbers have been exactly 50-45 on four out of the last seven days.
