Overview
The 1978 state‑senate elections left the Democratic Party in command of 43 of the 50 contested chambers, a net gain of seven chambers over the previous cycle. The Farmer‑Labor Party held five chambers with no change, while the Republican Party slipped to two chambers, a loss of two. The map’s gain‑loss shading highlights a decisive Democratic surge that flipped three GOP‑held chambers and two that were previously under the Federalist‑Progressive USA (FPUSA) banner.
What Flipped
Seven chambers changed party control. The Democrats captured Florida, Georgia, Louisiana, Kansas, New Mexico and Texas, all of which had been governed by either the GOP or FPUSA. Illinois was the lone loss for the Democrats, flipping to Republican control. These flips are illustrated on the map by the bright blue (gain) and red (loss) outlines, showing a clear regional pattern: the South and the Southwest moved toward Democratic majorities, while the Midwest saw a solitary Republican breakthrough in Illinois.
The National Picture
Across all state‑senate seats nationwide, Democrats now occupy 1,048 seats, Farmer‑Labor holds 706, the GOP holds 83, and the remaining 133 seats are split between the Constitution Party (51) and FPUSA (82). The Democratic plurality translates to a national seat advantage of 342 over the Farmer‑Labor Party and a commanding 965‑seat lead over the Republicans. This aggregate balance underscores the Democrats’ dominance in state legislatures, giving them a robust platform for advancing their agenda at the sub‑national level, while the GOP’s reduced chamber count limits its influence to a handful of strongholds.
