The reclaiming of the Wisconsin state Senate by the Democratic Party received some fanfare last month in the Badger State, but the extent of Democratic pickups in the state Senate and state Assembly is nearly unprecedented over the past half-century of Wisconsin state politics.
Democrats had controlled the 33-seat state Senate for 12 of the last 16 legislative sessions dating back to 1974, although Republicans had been the majority party since 2002. The 4-seat pick-up by the Democrats in 2006 (shifting a 19-14 deficit to an 18-15 advantage) was the second largest gain achieved by either party in the chamber dating back to 1960.
In the 99-seat state Assembly, the Democrats picked up 8 seats, reducing the GOP's 59-39 advantage (1 seat was vacant) to 52-47. This marked the second largest pickup in seats by either party in Assembly elections in nearly 50 years (in 1970 the Democrats gained 19 seats in a tidal wave election).
While virtually no one gave the Democrats a chance to win the Assembly, Republicans are indeed fortunate to have retained control: Democrats lost 3 districts by just 0.7 (District 47), and 1.1 (Districts 80 and 87) percentage points. A change in a few hundred votes in each of those districts would have meant the Republicans—who have controlled the Assembly since 1994—would have been on the short end of a 50-49 margin.
