The larger story may not be that one party or the other gained seats, but rather that the number of competitive seats dropped by 17, part of a decades-long trend of polarization among voters and consolidation of power by political parties.
In the current situation, just 34 of the 435 seats — less than 10% — are competitive districts, down 17 from when the maps were lasted used in 2020.
For the purposes of this CNN analysis, which applied 2020 election results to newly drawn districts, “competitive” refers to districts that either President Joe Biden or former President Donald Trump won in 2020 by 5 percentage points or less.
The competitive landscape of 34 districts in the CNN analysis is more than enough to swing control of the 435-member House of Representatives, and a wave in either direction could even put districts that were not competitive in previous elections in play.
Parties capitalized in specific places
But there are 10 fewer competitive seats in Texas.
Democrats there gained two seats.
That’s also the case in states such as Georgia, Missouri and Nebraska.
The process is changing for the better nationwide
Princeton professor Samuel Wang, who runs the Princeton Gerrymandering Project, factors multiple recent elections, instead of just 2020 Biden versus Trump data, into his analysis. He also notes a decline of competitive seats between 2020 and 2022, but an increase of competitive seats since 2012, which he views as “banner year for gerrymandering” for Republicans, although their advantage has gradually faded at the national level.
“One big reason is improvements in the redistricting process,” Wang told me, pointing to independent commissions and neutral map-drawing processes that have taken over in key states and what his organization views as better congressional maps in states such as Pennsylvania, Michigan, Virginia, North Carolina, and New York.
Fewer competitive districts. But there will be competition
Professional handicappers use a multitude of factors to determine which races might actually be in play.
“There might be fewer swing districts, but that doesn’t mean there are fewer competitive races,” Inside Elections editor Nathan Gonzales, a CNN analyst, told me in an email.
More safe Republican districts added than Democratic districts
There are marginally fewer districts that are very safe for Democrats and more districts where Biden won by between 2 and 7 percentage points. That suggests Democrats, more than Republicans, will be on defense in the new maps, perhaps even in races that are not on the competitive list.
A wave could reach deep into Biden territory
There is a difference between competitive seats, which have been declining, and competitive races, of which there can be many.
“What districts actually are ‘competitive’ changes from cycle to cycle,” Kyle Kondik, managing editor of Sabato’s Crystal Ball, told me in an email. “For instance, there probably will be several double-digit Biden seats that Republicans end up having a good chance to flip this year, particularly if the wind is at their back in the fall (we’ll see if that happens).”
He also made the important point that what seems like a safe district for Republicans or Democrats today, might look very different an election or two away.
KONDIK: Plenty of districts drawn to be safely Republican in places like Georgia and Texas got much more competitive over the course of the 2010s as Donald Trump pushed away a lot of traditional suburban Republican voters. Likewise, Trump made several typically Democratic districts in places like Ohio and Pennsylvania more competitive after he ascended to the top of the GOP and shook loose a lot of Barack Obama voters. Voter coalitions change over time, and they can change in ways that are hard to predict.
The district most like the country
Parties are switching control of Congress more frequently
Which way is the wind blowing?
Suddenly Democrats might have some reason for optimism in what is still expected to be an extremely tough political environment when control of Capitol Hill is on the line in November.
- In the Senate, they’re on the cusp of delivering on promises for climate and health care legislation that earlier this year had been left for dead.
- They’ve worked with Republicans to deliver bipartisan legislation on guns and to prop up the semiconductor industry.
- In the states, support for abortion rights in the red state of Kansas suggests the Supreme Court’s decision to overturn Roe v. Wade could be a potent election issue.
- Stronger-than-expected employment data suggests Americans who want to find jobs can find them.
But over all of this looms the persistent inflation that’s made American life more expensive and helped build a deep pessimism about the economy has helped keep Biden’s job approval at or below 40%, which is a telling indicator as more and more districts become more solidly partisan.
