About the 1974 Senate elections

Nixon left office in August 1974, and Gerald Ford's pardon of him a month later angered many voters. Inflation and a weak economy added to the Republicans' problems. Democrats won 22 Senate races to the Republicans' 11, gaining seats in Colorado, Florida, Kentucky, Ohio and Vermont while losing Nevada. Patrick Leahy became the first Democrat elected to the Senate from Vermont, and Gary Hart unseated Peter Dominick in Colorado. In Ohio, John Glenn, the former astronaut, won an open seat. Several Republicans survived by tiny margins. Milton Young held North Dakota by 0.1 points, Henry Bellmon kept Oklahoma by 0.5 points, and Bob Dole held Kansas by 1.7 points. In Nevada, Paul Laxalt beat Harry Reid by a few hundred votes. New Hampshire produced the closest Senate election in the country's history. Louis Wyman and John Durkin were separated by a handful of votes after recounts, and the Senate could not settle the dispute. The seat was declared vacant and a new election was held in September 1975, which Durkin won.
