Discrepancy Persists in Tracking Polls

With four daily tracking polls giving Obama, on average, a +5% national lead, Gallup still reports a substantial lead for Obama, at +11%, 51% to 41%. It's hard to say what accounts for this discrepancy, though variations in party affiliation weighting and likely voter models are partly to blame. Taking all five daily trackers into consideration, the Democrat's national lead is +5.8%--49% to 43.2%--down from the Democrat's +7% advantage earlier in the week.
