Redistricting

After the release of the Census every 10 years, each state redraws its congressional district lines to reflect changes in population. Some states do this process primarily through the state legislature, while others mandate a bipartisan or independent commission. But it's not just a once-a-decade exercise; whether due to court challenges or — as is occurring now in Texas and other states — a desire to consolidate party power, some states also engage in mid-cycle redrawing of their congressional maps, which can have major consequences for the balance of power in Washington.

Understanding the contours and candidates of House races is a big job, and no one has covered House races over the past forty-plus years like we have. That includes our meticulous work to provide comprehensive analysis each new redistricting cycle and what it means for every seat in the country.

See below to explore our analysis from the 2025-2026 cycle so far, as well as our work documenting every step of the 2021-2022 redistricting process.

Republicans are in the process of redrawing congressional district lines in several states, in an attempt to maximize their gains next November. In response, Democrats are attempting to redraw their map in California, and could benefit from a new map in Utah. Meanwhile, an upcoming Supreme Court decision on the Voting Rights Act could dramatically impact redistricting this cycle, and beyond.
