Can someone make a Missouri map of McCaskill% minus Obama% 2012?

Other than St. Louis County, St. Louis City and Jackson County, she did better by at least 22 points; that kinda skewed the color scale intervals, but you get the idea.

@ MilesC56: Is your map displaying the change in absolute percentages, or in two-candidate margins? I did some cross-checking on a randomly selected county (Nodaway in the North-West), where, according to this unofficial source,  McCaskill performed 17% better than Obama ..

President: R+ 27
Senate: D+ 12

The gap is 39 points.

In addition to Missouri, there have been two more Senate surprises in 2012, namely Indiana and North Dakota. Does anybody happen to have similar "US-Senate D minus Obama" maps for these states at hand?. It would be interesting to check whether they display patterns similar to Missouri.

It looks like the areas of lowest deviation are the Native reservations (which were already strongly Obama) and Williston- which I'm guessing was strongly R in the Senate race due to a large amount of voters being fossil fuel workers who recently moved there, i.e. less likely to bend D on farm issues, personality, etc.

Yeah, there was less room for Hietkamp to improve in the counties near the eastern border and near the reservations.

There was likewise a huge increase in turnout in those western counties.

The only county that Donnelly overperformed Obama by less than 10% was Lake, even there he did 9.92% better; for the sake of convenience I grouped Lakes in with the >10% counties so I didn't have to add an interval.
