People who have followed fundraising totals in South Dakota’s U.S. Senate race know the basic facts: Mike Rounds has raised by far the most, Nelson and Rhoden have raised the least, Weiland has been steady but unimpressive, and Bosworth has raised a lot of money from nationwide donors in unusual circumstances.
But here’s a way to visualize that fundraising at a glance. I used a tool called a heat map, which represents the density of points on a table, to map the cities the five candidates have raised money from. (This isn’t counting unitemized donations.)
Here, for example, is Stace Nelson's fundraising heat map:
(Larger interactive version) You can see Nelson has raised almost all his money in South Dakota, in a series of scattered clumps — not too much money in any one place. He also has a big clump in the Mitchell area, Nelson’s back yard.
Contrast that with Larry Rhoden's fundraising:
(Larger interactive version) Rhoden has a lot less support in eastern South Dakota, but dominates West River. Rhoden also has a teensy bit more nationwide support, but nothing significant.
Annette Bosworth, on the other hand:
(Larger interactive version) South Dakota is almost barren. Bosworth has raised a lot more money than Rhoden and Nelson, but far less in South Dakota. Instead, Bosworth’s map is dotted with yellow, reflecting a lot of scattered fundraisign around the country, but few real concentrations. She does have a disproportionate amount from Florida and the eastern seaboard, as well as the metro areas Denver and Chicago. All this fits with Bosworth’s direct mail-based approach of targeting conservative donors — often retired — around the country.
Here’s Rick Weiland:
(Larger interactive version) Weiland has a broad national base of support, as well as a fair amount of donations from South Dakota. He’s not as concentrated in a few South Dakota cities as Rhoden and Nelson are, but significant portions of the map are covered with yellow and red. Weiland also has a big cluster in Washington, D.C. — despite his lack of support from the Democratic Senatorial Campaign Committee — and is strong in Boston and San Francisco.
Finally, there’s Mike Rounds:
(Larger interactive version) Rounds has raised a lot more money than anyone, and that’s reflected on the map. He’s collected money from a huge swathe of South Dakota, with a particular concentration in the Sioux Falls area. Rounds has also taken in a lot of money in the nation’s big cities: D.C. (but less prominently than Weiland), Philadelphia, New York, Boston, Minneapolis, and Los Angeles.
Jason Ravnsborg and Larry Pressler have yet to report any significant fundraising.
