Ouch, the truth hurts department

In summary, they've been going all over the country visiting campaign
offices. They almost always find the Obama office bustling and the
McCain office deserted. The McCain people always claim they "just
missed" the huge mass of volunteers who the one or two volunteers left
swears, were just there.

and lest 'wingers whine that it's a liberal hit piece, note these two
paragraphs:

In Cortez, CO, we had Republican volunteers pose for action-shot
photos. The same in Española, New Mexico. Posed. For some time at the
outset, we were willing to give Republicans the benefit of the doubt.
They convinced us they were really working, and that we had just had
unfortunate timing. It wasn't until the pattern of "just missed it"
started to sound like a drumbeat in our ears that we began to grow
skeptical. We never "just missed" any of the Obama volunteer work,
because it goes on nonstop, every day, in every office, in every
corner of America.

and this one:

We haven't yet seen a single Republican canvasser. (The one in
Cortez, CO was staged; she said canvassing is the kind of thing she
would do, and we made a decision to do the picture because we were
concerned with not presenting "balance." There is no balance in the
facts.)
