History

Historical Context

The 1994 Republican Revolution saw GOP candidates win eight Senate seats, giving the party its first Senate majority since January 1987 and flipping the balance to 54-46 after two Democrats switched parties. That wave of high-stakes fundraising and cross-state endorsements mirrors today’s Kansas race, where Democrat Adam Hamilton challenges incumbent Roger Marshall with backing from former governors Mike Hayden and Bill Graves.
