4. The money ecosystem of US politics The network and organizational dimensions

5. From Lin and Lazer (2010)

6. Geography of money From Onnela and Lazer (2009)

7. Enormous regional inequalities… Per capita contributions, zip 66508 (Marshall KS) for 1999-2010: Per capita contributions, zip 10013 (New York City) for 1999-2010: $4.71 $178.48

8. Population density, market niches, and collective action If you can’t find a niche in Manhattan, you can’t find it anywhere… The potential of making contributions that are “noticed” The utilization of networks to mobilize people The existence of a critical mass for almost anything (who wants a fundraising party with 3 people?)

9. The Political-Money networks From Ruths and Lazer (2009)
