I've just found out that Jon Carson, Obama's National Field Manager, a Wisconsin native, has an MS in fluvial geomrphology from UCLA. Here's a TPM interview from right before the election.
From this article:
Carson eventually finished his master’s degree in fluvial geomorphology -- he studied sedimentation in a section of the Mississippi River off Goose Island -- and he and his wife, Rebecca, whom he met on the Gore campaign, left for Honduras, where Carson built water systems and taught surveying as a Peace Corps volunteer.Carson also worked for Tammy Duckworth in Illinois. He's never studied political science and says that his science background really helped with important number crunching. Sounds like a cool guy.
