(CNN) - Barack Obama holds a six point lead over John McCain in the latest CNN poll of polls.
The poll of polls, an average of five recent national surveys, shows the Illinois senator at 49 percent among registered voters nationwide with McCain at 43 percent.
“When you average the latest national polls, Obama appears to be slowly expanding his lead. He was ahead by four points before the Democratic Convention, and now he’s up by six,” noted CNN Senior Political Researcher Alan Silverleib.
“That said, we’ve seen swings of a point or two on a regular basis over the couple of months. The jury is still out on whether Obama will benefit from any sustained convention bounce. We’re also still waiting to see what — if any — impact the Palin pick and the Republican Convention will have on the race.”
