If Barack Obama is elected President on November 4th, it will be in large part because of the sophisticated way his campaign has communicated with the American public.

I was in Michigan this past weekend, and drove past the “North Oakland County Victory Office” of the McCain Campaign, just west of Pontiac, twenty miles north of Detroit. A placard near the street read “Get your McCain-Palin lawn signs here!” The building looked like a small bait shop, set back from the road, in the middle of a big parking lot with few cars. No one seemed to be there. On a Saturday afternoon. A month before the election.

This could have been a reaction against the McCain campaign deciding to give up on Michigan late last week. But when compared to what I’m reading about Obama’s organization, the two campaigns are running entirely different ground games. A few examples of what Obama’s been doing:

Here’s an ad that the bluegrass legend Ralph Stanley made in support of Obama. It’s in heavy radio rotation in Virginia:

Here’s a report from the Fulton (MO.) Sun, about the Obama campaign’s use of TTY devices to call hard-of-hearing voters.

Here’s a link to the iPhone Obama Application (pictured at right), which sorts contacts by state (putting battlegrounds at the top), and makes it easy for individuals to find their way to campaign events, make calls on behalf of Obama, or get details on the candidate’s take on particular issues.

The Obama campaign bought a tv channel on the Dish Network. Channel 73 will be playing all-Obama programming through the election.

Here’s some reporting on the campaigns from fivethirtyeight.com; a couple of bloggers have visited both campaigns’ offices throughout Colorado and Missouri. Key section:

Let’s be clear. We’ve observed no comparison between these ground campaigns. To begin with, there’s a 4-1 ratio of offices in most states. We walk into McCain offices to find them closed, empty, one person, two people, sometimes three people making calls. Many times one person is calling while the other small clutch of volunteers are chatting amongst themselves. In one state, McCain’s state field director sat in one of these offices and, sotto voce, complained to us that only one man was making calls while the others were talking to each other about how much they didn’t like Obama, which was true. But the field director made no effort to change this. This was the state field director.

The McCain offices are also calm, sedate. Little movement. No hustle. In the Obama offices, it’s a whirlwind. People move. It’s a dynamic bustle. You can feel it in our photos.

Finally, for those who think Obama’s been too reticent to hit McCain hard: think again. Much of the more aggressive and negative stuff is happening on a subterranean level (although that’s about to change with a national ad on McCain and the Keating Five). Spanish language commercials (radio and tv) are running in New Mexico, Colorado, and Nevada tying McCain to Rush Limbaugh, saying he has “dos caras,” or “two faces.” This morning I heard a report featuring a call from a Virginia Obama-supporter to an undecided voter. It began with a reminder that John McCain would be the oldest President ever elected. The caller then brought up the specter of McCain’s death, talked about Sarah Palin’s embarrassing interview with Katie Couric, and then asked the person on the other line if they really want her as their President. In national tv appearances and the debates thus far, in recognition of Obama’s campaign against “politics as usual,” the candidate and his running mate have avoided a negative or derisive tone or even challenging Palin. I think Biden probably could have field dressed Palin last week had he wanted to. Instead, he treated her and her substanceless winking — to paraphrase Garry Shandling– like how “Johnny Carson treated Charo.” (It’s only fair when acknowledging Palin’s winking to also note Biden’s botox. He did, however, answer a few of the questions). At the local level, the Obama campaign has a bit tougher.

There’s a direct correlation between the sophistication of the Obama ground game and the Democratic gains in affiliated voters. In Pennsylvania, registered Democrats outnumbered Republicans by 486,000 in 2000 and 580,000 in 2004. Now? 1.15 million. In Nevada, four years ago Dems trailed by nearly 5000 registrants. They currently hold an 80,000 voter edge. In Florida, the Democrats have added 130,000 more voters than the Republicans over the past four years. If you’re an Obama supporter, those numbers are very encouraging.

Other factors explain this swing, including the unpopularity of the current administration and the downturn in the economy. But it would be foolish to discount the effectiveness of the Obama machine in organizing its base, supporting voter registration (especially among the young), employing technology, and effectively tailoring its message to particular constituencies. Obama and Biden know who their audiences are, and how to speak to them.

Admittedly, I haven’t been following the McCain campaign as closely as Obama’s, but I’ve seen no evidence that there’s much innovation or energy at its core. Yes, Palin has fired up the Republican base. But has that led to more organizing or a flock of volunteers in key locations? Aside from McCain’s increasingly negative ads and his hope that the economy becomes less central to the campaign, a few yard signs are all I’ve really seen.
