This study examines the inclusion-moderation thesis within the context of Israeli populism, focusing on how government participation influences the communication styles of populist legislators. By analyzing a comprehensive dataset of tweets from Israeli lawmakers between 2015 and 2022, we explore whether holding office leads to a moderation of populist rhetoric. Our findings indicate that while coalition members generally exhibit reduced populist communication, this moderation varies significantly between ministers and backbenchers. Most importantly, in populist radical-right parties (PRRPs) backbench coalition legislators do not moderate: they maintain a populist communication style akin to their opposition counterparts. This research contributes to the understanding of populism in a non-European context and highlights the complexities of integrating radical parties into democratic governance, suggesting that moderation is not uniformly achieved across party lines.
