The recently released campaign contributions available at the FEC’s website (http://www.fec.gov/disclosurep/pnational.do) provide another measure (along with all of the recent polling we’re hearing) of each candidate’s support in Wisconsin and differences in the types of supporters. Note that I’m only exploring individual “hard” dollar contributions to each candidate. These totals don’t include regular or Super PAC contributions or the nebulous and more difficult to track “social issue” groups.

First, the contribution totals for both candidates (up to Oct 17, 2012):

Candidate # of contributors Total contributions $$ Average contribution
Romney 8,841 $3,831,521 $433
Obama 40,933 $4,409,612 $108

In dollar totals, Obama has a slight edge over Romney and, taken alone, would indicate numbers similar to the polls — a narrow edge in Obama’s favor. The number of contributors, however, reveal a substantial difference — Obama has almost five times as many individuals contributing to his campaign.

As maps, these numbers tell a similar story. The first maps show the difference between total dollars contributed and number of contributors by zip code in Wisconsin. Zip codes with blue circles indicate more contributions or contributors for Obama while those with red circles indicate more for Romney.
