Many of my friends who are election law scholars have been involved with one of the presidential campaigns this season in varied roles.
But this one is probably unique:

Spencer Overton, a law professor at George Washington University and expert on campaign finance, raised more than $500,000 for Obama’s presidential campaign, according to a database maintained by the government watchdog group Public Citizen. Overton also sat on Obama’s national finance committee.

The article notes that Spencer will be serving on on an Obama transition review team looking at the Justice Department. I am very happy to hear that.
