(CNN) – The CNN Poll of Polls has been updated to reflect a new AP-IPSOS poll. Sen. Obama now holds a five-point lead over Sen. McCain – 48 percent to 43 percent – with 9 percent of registered voters remaining unsure about their choice for president.
The latest CNN Poll of Polls is an average of the following four surveys: CNN/Opinion Research Corporation (July 27-29), AP-IPSOS (July 31-August 4), USA Today/Gallup (July 25-27), and Gallup tracking (August 2-4). The poll of polls does not have a sampling error.
The previous CNN poll of polls released earlier Tuesday showed Obama leading McCain by 4 percentage points.
