French right-wing opposition set to maintain Senate dominance

France's right-wing opposition is expected to maintain its dominance of the Senate in the upcoming elections, posing another setback for President Emmanuel Macron's ruling party. Unlike the lower house, the Senate is not elected through direct suffrage but by around 150,000 "grands electeurs" who are elected officials. The Senate composition reflects the traditional French political landscape, with the right-wing Republicans and the Socialists being the largest parties.
