Sommer was initially a member of the French Communist Party (PCF) and later of the Socialist Party (PS). He joined La République En Marche! (LREM) in 2017 and Territories of Progress (TDP) in 2020. In parliament, Sommer served as member of the Committee on Economic Affairs.^[2] In addition to his committee assignments, he was a member of the French Parliamentary Friendship Group with Bosnia-Herzegovina.

In July 2019, Sommer decided not to align with his parliamentary group's majority and became one of 52 LREM members who abstained from a vote on the French ratification of the European Union’s Comprehensive Economic and Trade Agreement (CETA) with Canada.^[3]
