"There is likely no hidden life raft in the undecided vote for John McCain," said Andrew Kohut, director of the Pew Research Center, which concluded in a recent survey that undecided voters likely will split about equally between the two candidates.
Data from the past eight elections indicate undecided voters are unlikely to break decisively for either candidate and dramatically alter Tuesday's returns, Kohut told Politico.
Pew's recent studies found that 8 percent of the 2008 electorate remained undecided, similar to its findings among registered voters in the last week of the 2004 election.
