CNN) – Barack Obama appears to be regaining his summer edge over John McCain according to the latest CNN poll of polls, which shows a swing of four points in the Illinois senator's favor in just over a week.

With less than seven weeks remaining until voters weigh in at the polls, Obama now holds a 2 point lead over McCain (47 percent to 45 percent), according to CNN's average of several recent national polls. Eight percent still remain undecided.

The latest polls also suggest Obama again holds the slim but clear advantage he held in August before both parties' conventions — one month ago, Obama held the same 2 point margin over McCain.
