Bill Clinton won the 1992 presidential election as the Democratic nominee, running on a platform of middle-class tax cuts and national healthcare reform. He relied heavily on his wife Hillary Rodham Clinton during the campaign. Clinton positioned himself as a defender of the middle class against incumbent President George H. W. Bush and independent candidate Ross Perot. However, after taking office in 1993, Clinton found it difficult to enact his agenda due to resistance from a Republican-controlled Congress following the 1994 midterm elections.
