Two things

A very smart horse-race observation from the Jed Report:

The polls are now inserting themselves as a major asset for Barack Obama.

It's not just that people like a winner [...] It's also that every single thing that John McCain does is now viewed through the prism of polling data that shows him to be in a desperate position indeed. It makes everything he does seem more political than it might otherwise appear, and as a result, it means that no matter what he says, his credibility is automatically discounted.

When you combine this dynamic with the fact that McCain's campaign has been thoroughly dishonest since at least this summer, he now faces a nearly impossible task: getting voters to believe anything he says.

And a nuts-n-bolts but inspirational piece from Zack Exley of the Huffington Post, describing the Obama organization and how it is reshaping how political movements are built and run:

Inside the Obama campaign, almost without anyone noticing, an insurgent generation of organizers has built the Progressive movement a brand new and potentially durable people's organization, in a dozen states, rooted at the neighborhood level.

The "New Organizers" have succeeded in building what many netroots-oriented campaigners have been dreaming about for a decade. Other recent attempts have failed because they were either so "top-down" and/or poorly-managed that they choked volunteer leadership and enthusiasm; or because they were so dogmatically fixated on pure peer-to-peer or "bottom-up" organizing that they rejected basic management, accountability and planning. The architects and builders of the Obama field campaign, on the other hand, have undogmatically mixed timeless traditions and discipline of good organizing with new technologies of decentralization and self-organization.

Long and a bit wonky, but worth a read.
