Gallup Daily

Reporting some tightening, a phenomenon seen in the other trackers (except Hotline) either yesterday or today, Gallup Daily Tracker is out. Here are their three scenarios:

Registered Voters
Obama 50
McCain 43

The numbers were 52-42 yesterday.

Expanded Likely Voter Model (Intent)
Obama 51
McCain 44

The numbers were 53-43 yesterday.

Traditional Likely Voter Model (Intent and past behavior)
Obama 49
McCain 47

The numbers were 50-45 yesterday.

Gallup comments:

One forthcoming event with the potential to affect voter sentiments is a 30-minute Barack Obama paid program, for which his campaign has purchased time on Wednesday night on a number of national broadcast and cable television networks.
