For comparison, I dug up a presentation (PDF) by Obama campaign manager David Plouffe from the same month.

The result: The Obama campaign was spot-on in its assessment of its prospects, while the McCain people were way off the mark. Let’s take a look.

First, here’s Davis’ perceived electoral map, just four months ago:

Looking at today’s RealClearPolitics map (below), we can see that every single toss-up state is now in Sen. Barack Obama’s column. While all the “Lean GOP” states have held, three of the “Solid GOP” states — Virginia, North Carolina and Indiana — have turned blue:

Meanwhile, Plouffe was announcing the Obama team’s plan to turn these red states blue:

Lo and behold, every one of these is now in Obama’s column, mostly by substantial margins.

Another slide in Plouffe’s presentation indicated the states in which the Obama campaign would be advertising early and extensively:

Admittedly, a few of these are still unlikely to go for Obama — Alaska, for instance, effectively came off the table when Gov. Sarah Palin joined Sen. John McCain’ticket — but for the most part, Obama’s strategy paid off.

Here’s proof:

Virginia, North Carolina and Indiana, which McCain considered in the bag, now lean Obama by 7, 2 and 2 points, respectively, according to RealClearPolitics.

Connecticut, which McCain hoped to nab, is going for Obama by 19 points.
