We thank the editorial team and referees at @electoralstudies.bsky.social, excellent research assistants, and most of all the hundreds of experts that completed our surveys and helped generate this data set.
The paper is here: doi.org/10.1016/j.el...
And the data can be accessed at chesdata.eu. 7/

Our short article pairs nicely with @sarahobolt.bsky.social et al’s introductory essay for the @jeppjournal.bsky.social special issue on the 2024 EP elections: doi.org/10.1080/1350...
And, as in previous waves, our teams have coordinated on question wording to facilitate party-voter comparison 6/

The note further illustrates that these measures of horizontal accountability appear closely related to the transnational cleavage, as the party families at the pole of this divide (greens and the radical right) are also furthest from one another on the measure of horizontal accountability. 5/

The 2024 CHES included for the first time questions to measure positions on executive constraints & judicial independence, key features of horizontal accountability. Here, the rad right party family stands out as much less likely to support constraints on executives & judicial independence 4/

We further report a sharp and sustained increase in the correlation between party positions on European integration and party stances on immigration, which indicates the emergence and durability of a transnational cleavage in European party politics. 3/

Within the note we show that while the economic left-right positioning of the radical right party family has not shifted markedly to the left overall, the economic positioning of parties within the family has become more diverse over time. 2/

How much do Britons and political scientists - via @chesdata.bsky.social - agree on parties' place on the left-right spectrum?

Green: -55 Britons vs -59 experts
Labour: -36 vs -24
Lib Dems: -23 vs -23
Cons: +51 vs +53
Reform UK: +69 vs +85

Scale where -100 is very left and +100 is very right

The CHES is a survey of national party experts to place parties on political dimensions. It is generally considered the gold standard of comparative party research.
The new data has just come you. You can check it out with the link below. Big thank you to the team!

We will compile the 1999-2024 trend file soon, but in the meantime, you can merge with 1999-2019 now. In the 2024, we added several non-CHES variables into the regular dataset (vote share, family, etc.).

Soon! We plan to release in February.

Note that EU support ranges from Euroskeptical (0) to pro-EU (6) and lrgen refers to the general left-right ideological dimension, ranging from 0 (left-wing) to 10 (right-wing).
