(CNN) – As the fate of the first head-to-head debate between Sen. Barack Obama and Sen. John McCain remains uncertain, CNN’s latest poll of polls shows the Democratic nominee with a 4 point advantage over his Republican rival. Obama has the support of 47 percent of voters to McCain's 43 percent, with and 10 percent unsure about their choice for president. In CNN’s previous poll of polls, released Wednesday night, Obama was ahead by 5 points – 49 percent versus 44 percent.
“Since the start of the financial crisis, Sen. Obama has held a small but clear edge in the horserace,” said CNN Senior Political Researcher Alan Silverleib. “Sen. McCain’s decision to suspend his campaign in the midst of this crisis can be seen as an attempt to regain the upper hand on the economy — an issue which so far continues to work to Obama’s advantage. The overwhelming majority of Americans are more concerned with the state of the economy than with any other issue.”
Thursday’s national general election poll of polls is comprised of the following four surveys: Marist (September 22-23), Fox News/Opinion Dynamics (September 22-23), Gallup (September 22-24), and Diageo/Hotline (September 22-24). CNN’s poll of polls does not have a sampling error.
