Enough for Obama and McCain?

If the turnout predictions reported by Boston.com's James Pindell turn out to be accurate — or, as he thinks, prove to be on the low side — then there should be enough independent votes out there to float Barack Obama and John McCain. Pundits have been looking at the independent vote as a zero-sum game, and as Obama has risen, McCain has dropped back a bit closer to Mitt Romney. But that may not be the way things work out.
