There are regional elections in two federal states here in Germany today (elections of any kind are always on sunday to make voting easier for people). Here are a few tidbits that might be weird or interesting to Americans:
Voter participation has been going down in both states, from about 70% to about 64%. About two thirds of all votes are mail-in votes.
In Rheinland-Pfalz the SPD (center-left) will probably keep governing as leader of a coalition with its governor Malu Dreyer, who has an approval rating of 80%.
In Baden-Württemberg, the Greens will likely keep governing with the center-right as junior partner. The Greens here are relatively conservative and work surprisingly well with the center-right. The far right apparently got 11.5%, more than their current rating in most other Western states but only half of what they usually get in the East.
Angela Merkel, about to leave office after 16 years as chancelor, has an approval rating of 64%.
And no, a high aporoval rating does not mean that people will vote for a popular politician's party. It means that people differenciate between the person and the party. For example, I never voted CDU and don't intend to ever do that but there are several CDU politicians I openly recognize as competent and of integrity.
Basically, almost every party can work across the aisle with almost every other party. A notable exception to this is the far-right which keeps drifting away from social mainstream and often flirts with conspiracy theorists and science denial (over here only the far-right questions corona or climate change, not the center-right or any of the other parties)
