It's only close if you think of this as a typical election. Typically the news might play up one side, but they generally report poll findings based on more honest samplings and analyzing of the internals.
This time, however, the left, including most of the pollsters out there, are DESPERATE to see Obama win.
Right-wingers, meanwhile, have been unenthusiastic about voting since 1988. Think they really loved, and needed to see, President Bush's second term, or President Dole, or President McCain? Nope.
But they're fired up in a way they haven't been in over a decade.
