New University of California President Jack Peltason will slip into the comfortable role of professor when he visits the Davis campus next week. A noted expert on the Constitution and author of a standard political science textbook, Peltason will drop in on Professor Gary Segura's "Elections and Voting Behavior" class from 4:40 to 5:15 p.m. on Thursday, Nov. 12, in Room 26 Wellman Hall. Peltason will talk with students about the election process and field questions. He'll address the UC Davis faculty just before the class, from 3 to 4 p.m. in the Main Theatre.
