I should know the answer, but I don’t, and people I’ve asked don’t know the answer, either. What does the French Senate do, how is it (s)elected, and would it matter one way or the other if it didn’t exist?
(Fortunately, I’ve never had to teach introductory French politics, so I don’t feel too guilty at not knowing the answer to this one. I’ll probably google for it after posting this and the surrounding bits and pieces. But if anyone wants to leap in, please do.)
