Those trackingpolls don't make sense anyway. One day, Obama increases on Rasmussen and Gallup but decreases on Ipsos, like today. And on other days it's completely reversed. These polls are all over the place.
These seemingly random and even contradictory fluctuations (different national tracking polls showing good results for Obama and Romney on the same day) are probably the best indication that the race has stabilized at the moment and there is no clear momentum for any of the two candidates at least on the national level.
