11/02/2008 - The final Pew Research Center poll of the 2008 presidential election gives Barack Obama a 49 to 42 percent lead over his rival, John McCain. Though still a significant lead, it's suddenly a much tighter race than Obama's 15-point lead from last week.
There are two things closing the gap, says Andrew Kohut of the Pew Research Center. First, McCain has made some gains among whites, independents and middle-income voters. But the other boost he's enjoying comes from narrowing the pool of responses from registered voters to likely voters.
