A national poll of likely voters out on the eve of the election gives Barack Obama a 9-point lead over John McCain.
The Marist Poll found 53% of those surveyed backing Obama, while 44% said they support McCain. Last week, the same poll gave Obama a 7% lead.
More than half of registered Republicans respondents say they made up their minds before the conventions, while slightly less half of Democrats said they did.
Fifteen percent of Republicans surveyed said the vice presidential selections was the biggest factor in their decision.
For Democrats, 17% say the debates cemented their votes.
