About this election
How the voting works
The Senate has 128 members serving six-year terms, renewed in full at each general election. Ninety-six are elected by state: in each of the 32 federal entities the party list that comes first wins two seats and the runner-up list wins one (the "first minority" seat), guaranteeing the opposition representation everywhere. The remaining 32 are allocated nationally by proportional representation from a single closed list. This design deliberately tempers majorities, which made the size of the 2018 result all the more striking.
