Comparing how many seats they have versus how many the 2020 presidential results would have suggested.
KEY POINTS FROM THIS ARTICLE
— As we head into a once-a-decade redistricting cycle, we analyzed which states have one party that is currently overperforming in its House delegation compared to that party’s share of the 2020 presidential vote.
— Overall, the GOP has notched notable overperformances in 19 medium-to-large-sized states, compared to 11 for the Democrats. However, the total number of excess seats for each party from these states is roughly in balance, though Republicans have a slight edge: 32 for the GOP, 28 for the Democrats.
— The three biggest sources of excess seats for the GOP today — Texas, Ohio, and Florida — could provide additional excess seats in the coming redistricting round, given the fact that each state has unified Republican control of state government. The Democrats’ options for squeezing out additional seats are more limited because many of their biggest sources of excess seats have a commission system for redistricting.
