Obama is 8 points ahead of McCain

A new CNN poll of polls, comprising six recently released surveys, ties the largest lead Obama has held over McCain this election cycle, and suggests the Republican presidential hopeful faces an increasingly difficult task to turn around voter sentiment by Election Day on November 4.

According to the new poll of polls, Obama leads McCain 50-42 percent with 8 percent still undecided.

That number incorporates new polls from ABC/Washington Post, Fox News/Opinion Dynamics, Newsweek, Reuters/C-SPAN/Zogby, Gallup, and Diageo/Hotline.
