Huge turnout forecasts a Democratic blowout. Obama owns the hope and change message, and having a wave of new voters suggests that his message caught on.
McCain’s blather about a late-campaign surge only brings more Obama people out in the hopes of staving McCain off from stealing the campaign at the last minute.
What it might do is run cover for GOP vote stealing. All McCain needs is a narrative, and an argument abut the liberal media bias, and he has a way to tamp down protest of the take. All it takes is the story – enough to encourage people to go back to the polls and fight again for a candidate, rather than an independent movement for social change.
