Blue Wave

The Redward Trend of States, Visualized

Check out our interactive data visualization of all state legislative chambers 2008–2018.

Something big happened after the 2010 midterm elections: the partisan balance of state legislatures all over the country swung like a pendulum to the right. This was no accident. It was the result of a few factors, key among which was the Republican REDMAP strategy, which targeted state legislative seats and chambers for Republican takeover. The strategy was extremely effective — all told, Democrats lost about 1,000 state legislative seats since REDMAP, and Republicans now control more than ⅔ of all state legislative chambers.

Sister District harnesses the energy, creativity and resources of grassroots volunteers across the country to restore Democratic majorities to state legislatures across the country. Borrowing from the concept of “sister cities,” our unique organizing model “sisters” each of our 65+ active teams to a couple of great Democratic candidates in specific swing legislative districts for fundraising and field support.

Our 2018 political strategy involves targeting three types of state chambers:

Blue Flips — Chambers where Democrats are down a handful of seats

Colorado Senate
Arizona Senate
Arizona House
New Hampshire Senate
Maine Senate
Blue Holds — Chambers where Democrats have a slim, fragile 1–2 seat majority

Delaware Senate
Washington Senate
Blue Inroads (“No Chamber Left Behind”) — Chambers in key battleground states that are unlikely to flip blue, often due to Republican gerrymandering, where gains this year can bust Republican supermajorities and/or have significant impact on post-2020 redistricting.

Michigan House
Michigan Senate
Pennsylvania House
Pennsylvania Senate
Florida House
Below, we provide charts that display the changes in our targeted chambers over time. In particular, take note of the significant partisan swings that occurred between 2010 and 2011, after the REDMAP elections. These visuals display the dramatic erosion in Democratic power at the state level over the past 8 years, and show why Democrats can no longer afford to look past state and local elections.

Blue Flips
Colorado Senate — Democrats controlled the Colorado Senate for most of the 2000s, but Republicans have made consistent gains since 2008 and now control the chamber by the narrowest of margins: one seat. Democrats currently control the House (36–29) and the Governor’s mansion. 17 of the 35 Senate seats, all 65 House seats, and the Governorship are all up for election this year.
