With a 3-year-old son, Robert L. Ehrlich Jr. and his wife, Kendel, know that life in the governor's mansion is not going to be all politics. Pizza, popcorn and parties have to be on the agenda, as will be teaching children about democracy. Thus, the Ehrlichs, joined by his running mate, Michael S. Steele, and Steele's wife, Andrea, hosted about 460 kids and their parents Saturday at a children's inaugural party at Howard Community College in Columbia. The event began five days of celebration welcoming Maryland's first Republican governor in 34 years.
