History

Late 20th century

This section needs expansion. You can help by adding to it. (October 2021)

Connecticut's dependence on the defense industry posed an economic challenge at the end of the Cold War. The resulting budget crisis helped elect Lowell Weicker as governor on a third-party ticket in 1990. Weicker's remedy was a state income tax which proved effective in balancing the budget, but only for the short-term. He did not run for a second term, in part because of this politically unpopular move.[98]

In 1992, initial construction was completed on Foxwoods Casino at the Mashantucket Pequots reservation in eastern Connecticut, which became the largest casino in the Western Hemisphere. Mohegan Sun followed four years later.[99]
