(CNN) - A new average of the most recent national polls suggests Sen. Barack Obama holds a 6-point lead over Sen. John McCain.

The CNN Poll of Polls, compiled Friday morning, indicates that 49 percent of Americans say Obama, D-Illinois, is their choice for president, with 43 percent backing McCain, R-Arizona. Eight percent of those questioned are undecided.

The previous edition, compiled Thursday, indicated Obama had an 8-point lead over McCain, 50-42 percent.

This edition of the CNN Poll of Polls averaged four surveys: an American Research Group poll conducted October 11-13; a Reuters/C-SPAN/Zogby survey taken October 13-16; a Gallup poll conducted October 13-15; and a Diageo/Hotline survey taken October 13-15.

McCain is keeping the race close in Ohio.

(CNN) – Pennsylvania may be slipping from John McCain’s grasp, but the Republican nominee is keeping the race close in the neighboring battleground state of Ohio – a state that no successful GOP presidential contender has failed to win.

CNN's new Ohio poll of polls shows Barack Obama leading McCain by three points, 49 to 46 percent. Five percent of the state’s voters were unsure about their presidential pick.

The network’s last Ohio poll of polls, released October 9, showed Obama leading McCain by four points, 50 to 46 percent. In the September 21 poll of polls, Obama led McCain by a single point, 47 to 46 percent.

Republican VP nominee Sarah Palin is slated to stop in Ohio Sunday - the third time on the past week week the GOP ticket has visited the state.

The Ohio general election "poll of polls" consists of four surveys: Ohio Newspaper Poll/University of Cincinnati (October 4-8), ARG (October 4-7), CNN/Time/ORC (October 3-6) and ABC/Washington Post (October 3-5). The poll of polls does not have a sampling error.

(CNN) – The match-up between Sens. Barack Obama and John McCain is tightening, according to CNN’s latest poll of polls.

Obama now leads McCain by four percentage points – 47 percent to 43 percent - with 10 percent undecided about their choice for president. Since the previous CNN poll of polls released Wednesday, Obama has dropped two percentage points – from 49 percent percent previously to his current support level of 47 percent – while McCain’s support remains steady at 43 percent since Wednesday.

“While there are indications that McCain may be closing in on Obama, we’ve seen these sorts of fluctuations in the polling average before,” cautioned CNN Senior Political Researcher Alan Silverleib. “McCain has not broken out of the low to mid-40s all summer. He has to hope that the combination of the Palin pick and a well-received acceptance speech tonight will somehow change the race’s fundamental dynamics, which so far continue to favor the Democrats.”

CNN’s August 29-September 3 national general election poll of polls consists of the following five surveys: CBS (September 1-3), Gallup (September 1-3), Diageo/Hotline (August 29-31), American Research Group (August 30-September 1), and CNN/Opinion Research Corp. (August 29-31). The poll of polls does not have a sampling error.

A new CNN poll of polls shows Obama's lead is dwindling.

(CNN) - In what could be an ominous sign for Barack Obama just days before he is formally named the Democratic presidential nominee, a new CNN poll of polls out Tuesday shows the Illinois senator's lead over John McCain has been cut in half in recent days.

According to CNN's average of several recent national surveys, Obama's lead is now a slim 3 points over the Arizona senator, 46-43 percent - half of his advantage in a CNN poll of polls one week ago, and down from a high of 8 points in mid-July.

The latest poll results come amid increased attacks from McCain on Obama's readiness to be commander-in-chief and the re-emergence of national security worries among voters in the wake of the Georgia crisis.

“Over the last week, we’ve seen Sen. Obama’s lead in the poll of polls cut in half,” noted CNN Senior Political Researcher Alan Silverleib. “This change was likely driven by a renewed focus on foreign policy after Russia’s invasion of Georgia, as well as by Sen. McCain’s willingness to launch more aggressive attacks against Obama on issues such as off-shore drilling."

A Los Angeles Times/Bloomberg poll out Tuesday evening was the latest national survey to indicate Obama's lead is dwindling, putting the Illinois senator ahead of McCain by only 2 points, well within the poll's margin of error. The CNN Poll of polls also includes new surveys from Quinnipiac and Gallup.

But the recent downturn in the polls for Obama may not last - the Democratic White House hopeful is headed for a week of what is likely to be overwhelmingly postive coverage as he names his running mate and officially accepts his party's presidential nomination.

"The big question now is whether Obama can successfully regain control of the campaign agenda as we head into the Democratic convention," Silverleib also said.

Barack Obama is up by 6 points in the latest CNN poll of polls.

(CNN) – Barack Obama continues to hold a solid lead over John McCain with just over 80 days remaining until the presidential election, a new CNN poll of polls shows.

According to the average of several recent national polls, Obama registers 47 percent among registered voters nationwide with McCain at 41 percent.

That lead has basically held steady over the last two months: A CNN poll of polls on June 20 also had the race at 6 points, 46 percent to 40 percent.

The national general election poll of polls consists of four surveys: Pew (July 31-August 10), CBS (July 31-August 5), AP-IPSOS (July 31-August 4), and Gallup tracking (August 10-12). The poll of polls does not have a sampling error.

WASHINGTON (CNN) – Call it a numbers game. With 87 days to go until the presidential election, our latest CNN Poll of polls shows Barack Obama leading John McCain by five points, 46 percent to 41 percent, with thirteen percent of Americans undecided.

The Poll of polls released Wednesday found an indentical result.

The CNN Poll of Polls is an average of the latest national polls. Our newest edition consists of three surveys, a CBS poll taken from July 31 to August 5, an AP-IPSOS survey conducted from July 31 to August 4, and a Gallup tracking poll taken from August 5 to August 7. Because it’s an average of a number of surveys, our Poll of polls does not have a sampling error.

As we always caution, the presidential election is not a battle for the national vote - rather, it’s a state by state fight for electoral votes. While national polls are important, they are far from the only barometer in determining where the presidential contest stands right now.

(CNN) – Barack Obama’s advantage over John McCain remains unchanged – but some voters for both candidates seem to be slipping back into the undecided column, the latest CNN Poll of Polls suggests.

Obama now leads Clinton by 1 point nationally.

(CNN) - The Democratic presidential race is tightening nationally, according to a new CNN average of several recent polls.

Obama's lead is now down to 1 point over Clinton nationwide, 45 percent to 44 percent, in CNN's "poll of polls." That margin is down 3 points from another CNN poll of polls conducted two days ago. In that analysis, Obama led Clinton 47 percent to 43 percent. The margin is also considerably lower than an April 18 poll of polls that showed Obama with an 11 point lead.

The poll of polls consists of three newly released national polls from Fox News/Opinion Dynamics, Gallup, and Newsweek. There is no margin of error on the poll of polls.

Both the Fox News poll and the Gallup poll were conducted partially after Obama's former pastor, the Rev. Jeremiah Wright, made a fresh round of controversial comments earlier this week.

The Fox News poll also appears to show Obama no longer has an edge over Clinton among independent voters. In head-to-head match ups, presumptive Republican nominee John McCain wins independents by a 4 point margin over Clinton (42-38 percent) and by a 10 points over Obama (47 percent to 37 percent).
