In other political developments last week:
≫ Governor Harold E. Hughes of Iowa, who rose from a truck-driver's cab and the captivity of alcoholism to become a successful (and abstemious) Democrat in a traditionally Republican state, announced that he will seek a third two-year term rather than try to unseat Republican U.S. Senator Jack
Miller. Hughes, 43, ran ahead of Miller 3 to 1 in a public-opinion poll this fall. He wants to stay in Des Moines a while longer, however, to see through proposed amendments to the state constitution that would reapportion the legislature and reorganize the state government.
