The centrist political group led by Hervé Marseille, president of the UDI, has not gained strength following the recent Senate elections. While the Republican-aligned group appears to be heading toward a stable position, the coming days might bring unexpected developments in the political landscape. The Union Centriste (UC) is uncertain whether it will claim the symbolic position of the second-largest group in the Senate, behind the Republicans, a title currently held by the Socialists. The group, which has 59 members, is not expected to significantly increase its numbers. Internal sources suggest the group could have between 58 and 60 senators after the elections, which saw the emergence of a group representing the National Rally (RN) but did not drastically change the overall political balance. Although the UC managed to re-elect several of its current senators, including Françoise Gatel, Bernard Delcros, Sonia de la Provôté, Hervé Maurey, Pascal Martin, Annick Billon, and Philippe Folliot, there were also notable setbacks. For example, in the Doubs region, the UC lost one of its two seats to the Socialists. The merging of the left-wing parties was also a factor in the defeat of outgoing senator Annick Jacquemet. In the Aube region, another change took place, with LR deputy Valérie Bazin-Malgras succeeding the centrist Évelyne Perrot. The next few days will be crucial for the UC, as the Senate is a place where alliances and political outreach are most active, especially among the central groups. This dynamic is likened to "mercato," a term often used in Italian to describe the market or the movement of players between teams, indicating that the political landscape could shift as groups with similar values interact and influence each other. The recent Senate elections may signal a pause in the centrist group's growth, which had increased from 54 members in 2020 to 57 before the 2023 renewal. After the 2020 renewal, the group dropped to 56 members before attracting new members in the following years, reaching 59. Despite the formation of an RN group, Hervé Marseille emphasized that there is a "majority" in the Senate and reiterated the importance of the Senate in stabilizing institutions. He stated that the Senate's role in bicameralism has been proven to be relevant in maintaining institutional stability.
