The Democratic candidates flipped both of Georgia's Senate seats, previously held by Republicans, in the 2021 runoff elections.
Such a situation where both Senate seats of a state change party in a single election should be rather uncommon since:
- both Senate seats have to be up in a single election (meaning that at least one has to be a special election)
- both Senate seats have to flip
So, has this happened before? If so, how many times?
