Normally, I can't bring myself to visit the website of the enemy, but I was curious to see just how many campaign offices the Romney team had in comparison to President Obama. Recently, Jim Messina stated that their voter outreach effort this time around was going to, "make 2008 on the ground look like 'Jurassic Park'".
Here is the side by side comparison of campaign offices (swing states only)
Obama Romney
Missouri 2 7
Michigan 20 22
New Hampshire 22 7
Minnesota 12 zero
Colorado 55 13
Florida 80 46
Ohio 79 36
Pennsylvania 39 18
Virginia 40 29
Nevada 25 10
North Carolina 49 23
New Mexico 11 7
Iowa 65 13
Wisconsin 52 23
TOTAL: 551 254
As we can see, Obama has a greater than two-to-one advantage in terms of campaign offices. The reason this is significant is because campaign offices are organization centers for the ground work - canvassing neighborhoods, registering voters, and getting quality face time with undecideds to explain the various policy positions of the candidates.
One of the things that jumps out at you by looking at this list is the overwhelming advantage Obama has in states like Colorado and Iowa, at least in terms of campaign offices. These offices drive the get out the vote effort on election day. The more campaign offices you have in a state, the less time each volunteer has to spend contacting people on the call lists. Now this is not to say that just because one candidate has more campaign offices, he is guaranteed electoral success. But in a close election, the campaign that has a better GOTV apparatus has a better chance of winning.
In the 2008 election, I worked out of a campaign office in Henderson, Nevada. A GOTV partner and I went out to contact voters to make sure they voted. It was all supremely well organized. Back then, the Obama campaign had four or five campaign offices in the Las Vegas area. This time, they have twenty. Mitt Romney has three.
