Historical Context

In 1994, after President Bill Clinton’s approval slipped to about 37 percent, Newt Gingrich’s Contract with America helped Republicans capture eight Senate seats and 54 House seats, ending twelve years of Democratic control of Congress. The swing created the first unified GOP majority since 1952 and now frames today’s tight Senate races and the 2024 control battle.
