Gallup:
The nine percentage point lead in Oct. 4-6 tracking matches Obama's highest to date for the campaign, and the highest for either candidate. Obama led McCain by 49% to 40% near the tail end of his international trip in late July. Obama has now held a statistically significant lead since Sept. 24-26 polling and has not trailed McCain since Sept. 13-15, roughly coinciding with the intensification of the financial crisis.
