Good thing to keep in mind when looking at the chart above. Also puts 1958 into perspective cuz Republicans started with 201 seats.

Replying to @lennybronner
You have to control for the number of seats the party held going into the election. The biggest reason Dems lost so many more seats in 2010 than in 2022 is that they had so many more to lose! If you just made the Y axis seats won rather than seat change, that wouldn't matter.

That being said, Eisenhower in 1958 and Obama in 2010 "under-performed" their approval rating in the House by more than Biden "over-performed" last year, but it's pretty close (and more likely to do with the simple model)

I realize this is only looking at approval rating (and the House), but, using this very simple model, this is the largest positive deviation from expectation for the presidents party in the House since WW2.

This is obviously more reliable in presidential elections, but recent midterms have been centralized enough such that we were able to get away it. This particular midterm raises the question whether our model would have performed better with a "tossup" fixed effect.

This decentralization raises interesting questions around election night modeling (like the needle or our fuzzy bars). At least in our case, the model depends on patterns holding across the country since what is happening in one state informs predictions in other states.

As our understanding of what happened in 22 takes shape, this is another piece of analysis that underscores 1) This was a very decentralized midterm 2) Turnout in competitive races looked more like 20/18 3) Small slippage for Dems amg Black voters. Not huge, but interesting twitter.com/jon_m_rob/stat…

New: Compton, a city known for its Black culture, has flipped majority Latino — but its leadership remains all Black. My piece on this complicated city and the group of Latino vaqueros who are pushing for change:

Initial results have always tilted towards the AKP. This has to do with how the count is done. In past elections, we’ve seen Erdogan start at around %60-65. Who knows what will happen but let’s wait for a higher % of the count for the educated analysis and hot cakes.
Quote Tweet
As we expected: the first ballots open show a huge Erdogan lead. This is the usual; as I stated earlier this will change over the night. It is going to be a long night but we all need to be patient.

Great piece on voter registration trends among young voters and what we can and can't say about what these trends means for the future

I used to tell people that data science was the opposite of science and I was only partially kidding
Quote Tweet
This is a massive issue in data professions and it seriously stymies creativity, quality, and knowledge generation. The prevailing pedagogy of data science convinces folks to start with some data and work up, rather than starting with a vision and working down. twitter.com/rlmcelreath/st…

one of my favorite facts: since the president of France is a co-prince of Andorra, Andorra is the only country in the world with an elected monarch who is democratically elected by the population of a different country.

That divergence probably accurately reflects the uncertainty for an election that is 19 months away in our current moment
Quote Tweet
2024 has a pretty sharp divergence so far between what the institutional forecasters and what the Twitter Nerds believe - most notably on WV and TX.

2018 to 2022 was the first time that the non-Hispanic White share of the electorate went up between two comparable elections since 1986-1990
Quote Tweet
The electorate overall had the highest share of non-Hispanic Whites since 2014. Midterm elections tend to see a whiter electorate, although 2018 was a bit of an aberration. I fully expect to see a sizable drop in the White share of the electorate in 2024 compared to 2022

added some more findings to the story: Turnout sagged among college-educated voters (...) though it was particularly large among Black college graduates, dropping from 73 percent in 2018 to 60 percent in 2022 (incl. 20 point drop for Black voters w/ college degree)

This along with Democrats beating expectations last year is more evidence that racial polarization is continuing to decrease

election data friends: when adjusting for CPS over-reporting turnout, why do we adjust the weight based on the turnout rate instead of the raw number of voters? If we do the latter we get the same turnout rate (up to rounding) and we also get the raw counts for free

hmm I'm not sure I believe this. Obviously a different kind of election model, but it took us around a year and a half before we produced the core of an election night model that we were really happy with.

The communists recent surprise result in Salzburg seems to have given them national momentum. The Austrian left was hoping to put together a coalition of social democrats, greens and liberals after the next election (like Germany). It's hard to see them do the same with the KPÖ.

fun regular reminder that Donald Trump got more votes in California than in any other state in the United States.

8. The House wants Minnesota to hand our presidential electoral votes to whoever wins the national popular vote. No one seems to care that future presidential elections will be decided completely by large cities on the coasts like New York and Los Angeles.
