Risky group appeals? 😱 Our paper on how citizens react to electoral promises targeted at different social groups is published in @ejprjournal.bsky.social With @iguinaudeau.bsky.social & @elisadeisshelbig.bsky.social 🚀 🔓 doi.org/10.1017/S147...

💫 New paper! @elisadeisshelbig.bsky.social, @theresmatthiess.bsky.social & I are happy to see our new paper published in open access with the @ejprjournal.bsky.social Do group-targeted campaign pledges pay off electorally? We test this with a preregistered survey experiment in Germany.

Really interesting study! The impact is probably even more crucial in countries using majoritarian systems such as France.

New paper out in the @thejop.bsky.social (w/ @christinagahn.bsky.social) Do opinion polls shape election results? Using both cross-national data and a survey experiment, the answer we find is yes - though it depends on how we communicate polling results. www.journals.uchicago.edu/doi/10.1086/...

Parties increasingly promise benefits to specific groups, (parents, pensioners, rural residents...) This may make promised benefits more visible, concrete and personally relevant – and thus mobilize beneficiaries more effectively.

Can France still be governed under its current electoral system? After almost two years of parliamentary fragmentation, the situation remains unsettled: huge frustration, no stable majority and a presidential election already casting its polarising shadow over parliamentary life.

The main obstacles are thus political: sticky prejudices about proportional representation, self-preserving reflexes among politicians elected under current rules, and the short-sighted belief that the majoritarian system might eventually deliver an absolute majority to one’s own camp.

But it was striking yesterday to see the breadth of the coalition behind the discussion. The event was initiated by MPs from four different parliamentary families and involved one former President and two former Prime ministers from different parties. Something is clearly moving 👀

A proportional system would not magically create a culture of compromise. But it would reduce our current reliance on barrage voting, clarify electoral outcomes and help making governments more broadly representative – and therefore more legitimate and able to govern.

… yet the system no longer reliably delivers what was supposed to justify these costs: stable majorities, clear mandates, and effective government. Governments are increasingly unstable and incapable of governing.

Pre-electoral alliances (vital to survive in the current system) trap parties in bloc-based strategies that are very costly to revise post-election and hinder the search for majorities. At the same time, the “victories” produced by tactical withdrawals and barrage voting remain deeply ambiguous.

The current system increasingly combines the worst of both worlds: highly disproportional results (parties have been able to win absolute majorities with less than 1/3 of first-round votes), huge shares of votes not translated in any form of representation...

What struck me most was that the debate has moved forward: proportional representation is no longer discussed as a mere abstract or value-based choice. The debate has become more precise: which electoral system could help France move out of the current crisis?

A cross-party bill proposes to introduce a mixed compensatory system for legislative elections (inspired by the German and NZ models): this would keep 577 MPs, 347 elected in single-member constituencies and 230 elected from national compensatory lists. www.assemblee-nationale.fr/dyn/17/dossi...

This is politically dangerous. The more voters feel that their strategic mobilisation is misread, the greater the risk that they end up abstaining or refusing to contribute to the “barrage” next time. The far right may then not even need to convince a majority.

The perspective of 2027 makes this pressing. If the far right is once again in a position to win many 2nd-round contests, preventing the majoritarian system from amplifying its support will rely on “barrage” voting: voters mobilising not for their preferred candidate, but against RN.

How long will the barrage hold? It repeatedly asks citizens to support candidates they may dislike and who may later behave as if they had received a positive mandate to implement their programme.

The 2026 budget, in particular, could only be adopted through the use of Article 49.3, a constitutional device that allows the government to pass a bill unless a no-confidence motion succeeds, i.e. without a vote.

In theory, the current parliamentary fragmentation should encourage negotiations to construct majorities. But institutions, electoral incentives and political habits keep pushing parties to behave as if unilateral government remained possible.

Over the past couple days I have seen so many accounts that *never* post anything political, speak out against ICE. I sincerely hope Dem leaders don’t let up. This momentum is everything.
