Before 1992

The Delaware House was competitive during the early 1900s. It flipped partisan control 10 times between 1912 and 1938. Republicans maintained control from the 1938 election until 1954. After that election, the chamber continued to alternate control, although not as frequently. From 1954 to 1984, control flipped six times and ended in a Republican advantage that would last another 24 years.
