Democrats won open Republican-held governorships in Arkansas, Colorado, Massachusetts, New York, and Ohio; and they defeated Republican incumbent Bob Ehrlich in Maryland while retaining all of their seats, including their lone open seat in Iowa. Meanwhile, Republicans held open seats in Florida, Idaho, and Nevada, as well as Alaska, where incumbent governor Frank Murkowski was defeated in the primary. Voters in the United States territories of Guam (then-Republican) and the United States Virgin Islands (then-Democratic, but term-limited) also chose their governors and voters elected a new mayor for the District of Columbia, the District's chief executive.
