In 1956, thanks in part to the popularity of Dwight Eisenhower, Republicans ruled Connecticut.
In that year, Prescott Bush (R) defeated Rep. Thomas Dodd for a U.S. Senate seat, joining Sen. William Purtell (R).
All six congressional districts were won by Republicans. Dodd has been the lone Democrat, but his open 1st District seat was won by Republican Edwin May.
Republicans also dominated the legislature. They controlled the House, as they almost always did in those days when every municipality had exactly two state representatives, by a huge margin, and won the state Senate by a margin of 31 to 5. The only Democrat left in office was Governor Abe Ribicoff, who suddenly found himself all but irrelevant.
1958 was a different story altogether. Democrats surged. The incredibly popular Ribicoff handily won re-election, and took the entire ticket with him. Thomas Dodd won Purtell's Senate seat. All six Republican members of Congress were turned out and replaced by Democrats. Edwin May would be the last Republican to represent the 1st District. Better yet for Democrats, they retook control of the state Senate and won the state House of Representatives for the first time since the Civil War. That remarkable victory set the state for fundamental reforms which would change the way Connecticut was governed. Republicans, who just two years before seemed to have a lock on Connecticut, suddenly found that they had nothing at all.
