(CNN) — Barack Obama holds a 4-point lead over John McCain in the latest CNN poll of polls.
The new average of the three most recent national surveys of registered voters shows the Illinois senator at 47 percent with McCain standing at 43 percent. About 10 percent say they are undecided.
The margin between the two presidential candidates has narrowed slightly over the past week: in a CNN poll of polls taken July 16, Obama and McCain were separated by 6 points.
The latest poll of polls includes recent surveys from Gallup, NBC/Wall Street Journal, and ABC/Washington Post.
