Since the economic crisis, the race has been relatively stable, with Obama having an average lead of 3 to 4 points in the daily trackers.
Today, this has changed. With the daily trackers including two days of polling after McCain's decision to suspend his campaign, Obama jumped 1.75% and is now beating McCain by 5%. This is the largest average lead and jump since all four trackers were up.
Today 's tracker results:
Gallup: Obama +3
Daily Kos/Research 2000: Obama +5
Diageo/The Hotline: Obama +7
