It's been an eventful two weeks for William Keith Bostic Jr. Last week, the 22-year-old Texas native was graduating from the University of Michigan with President Barack Obama delivering his commencement speech. This week, he's making moves to run for mayor of Ann Arbor. Bostic was a late surprise this week when his name appeared on the list of candidates seeking the mayor's seat in this year's elections. He's circulating petitions to run as an independent in the November general election. "I really have nothing to lose," he said.
