A member of The Republicans (France) (LR), Matthieu Bloch was elected mayor of Colombier-Fontaine in 2020, after winning the municipal elections against Philippe Geoffroy's list.[2]
In the 2022 legislative elections, he was the LR candidate in the 4th constituency of Doubs. He opposed the Republican front but announced that, personally, he would vote for the candidate who knew the area best. Frédéric Barbier was narrowly defeated by the National Rally candidate,Géraldine Grangier.[3]
In 2023, Matthieu Bloch became departmental secretary of the Doubs Republicans federation.[4] He is thus the party's “second-in-command” in the department, behind the federation's president, Annie Genevard.
In the 2024 legislative elections, Matthieu Bloch supports the alliance between LR and RN, even though he does not officially approve of the method used by LR president Éric Ciotti. He himself is a candidate for this alliance between Union of the Right for the Republic on the right and the RN, despite the reluctance of some local RN activists, in the 3rd constituency of Doubs, around Montbéliard, where the outgoing Renaissance deputy, Nicolas Pacquot, was narrowly elected in 2022.[5] Matthieu Bloch came out well ahead in the first round (44.4%), ahead of the outgoing deputy and the New Popular Front candidate; although the latter withdrew “to block the RN,” Matthieu Bloch was elected deputy with 50.8% of the votes cast.
