Here's something interesting. I took the two party vote totals for the presidential and senatorial races. After adjusting for the statewide margins in the races (if this wasn't done, Coleman would've outperformed Franken in every state house district in the metro area
), I subtracted the McCain vote total from the Coleman vote total, to get this map:
Where yellow is Coleman underperforming McCain and green is Coleman overperforming McCain. (white is within 0.5 points, and each band is one percentage point, so the lightest yellow is 0.5-1.5 points underperformance, the next one is 1.5-2.5 points underperformance, etc.)
In general, the metro had Coleman overperforming McCain by about 1 point (relative to the overall margin, so about 6.3% total).
I think that 45B is St. Louis Park, while St. Paul is more Coleman because he was mayor there. This map seems to be in concordance with my "Franken Alienated Suburbanites" hypothesis
(or perhaps Obama was just a particularly good candidate for the western suburbs)
Here's the Obama-McCain map overall:
