Like the other 576 French constituencies, it elects one MP using the two-round system, with a run-off if no candidate receives over 50% of the vote in the first round.

For its first election in 1958, the victorious candidate is Gabriel de Carville, a former military and general councillor for the canton of Marigny.

From Daillet's party, the UDF candidate is Georges de La Loyère, from Montreuil-sur-Lozon, and Jean-Claude Lemoine, from the RPR.

Philippe Gosselin, the former Lemoine substitute and mayor of Remilly-sur-Lozon, is the main right-wing candidate for the UMP in 2007.

Christine Le Coz, the socialist general councillor for the canton of Saint-Lô-East, reaches almost 47.5 % of the vote during the second round.

However, Gosselin gets his fourth mandate in 2022 on a wide margin, exceeding 68% of the vote, opposed to a green candidate, supported by the left-wing NUPES alliance.
