(CNN) - The bounce John McCain received in national opinion polls following his party's convention and the selection of Sarah Palin to the GOP presidential ticket appears to have evaporated, a new CNN poll of polls suggests.
In the latest CNN survey of several recent national polls, Obama and McCain are locked in a dead heat at 45 percent each with 10 percent who remain undecided with 50 days remaining until Election Day.
“When we average the latest national polls, it is increasingly clear that neither candidate has any serious momentum at the moment,” said CNN Senior Political Researcher Alan Silverleib. “The convention bounces have faded and left us with a dead heat. Even though we are now in the final stretch of this historic marathon campaign for the presidency, the White House is still genuinely up for grabs.”
CNN's latest poll of polls consists of three recent surveys: Newsweek (September 10-11), Gallup (September 12-14), and Diageo/Hotline (September 12-14). It does not have a sampling error.
