Pew’s final survey indicates that the remaining undecided vote breaks slightly in McCain’s favor. When both turnout and the probable decisions of undecided voters are taken into account in Pew’s final estimate, Obama holds a 52% to 46% advantage, with 1% each going to Ralph Nader and Bob Barr.
The survey by the Pew Research Center for the People & the Press, conducted among 3,402 adults who were interviewed on landline and cell phones, finds that since mid-October, McCain has made gains among young voters, although they still favor Obama by a wide margin (by 61% to 36% among those ages 18 to 29). The Republican candidate has also made gains among political independents and middle-income voters. Obama still maintains a modest lead among independents, while middle-income voters are now evenly divided.
