(CNN) - As Election Day inches closer, Barack Obama continues to hold a significant lead over John McCain, according to CNN's average of several recent polls.
The Illinois senator now holds an 8-point lead over McCain in the latest CNN poll of polls, 50 percent to 42 percent. That lead is 1 point lager than it was in Wednesday's poll of polls.
The national general election poll of polls consists of four recent surveys: Fox/Opinion Dynamics (October 20-21), Reuters/C-SPAN/Zogby (October 20-22), Gallup (October 20-22) and Diageo/Hotline (October 20-22). The Poll of Polls does not have a sampling error.
