Anyway, I mostly agree with you, just fyi regarding the german green party: Annalena Baerbock was their chancellor candidate, Habeck was effectively what in the US would be a president's running mate. A duo, but Baerbock was iirc always going to be chancellor if the greens got a majority. And yes, they have joint leadership of the party.

That policy has to do with the german voting system, where each party has to provide a list of candidates for each state. Then according to how many votes the party gets, proportionally many people from that list get into the Bundestag, the list is in order. And that's the one that had to alternate.

The greens as of last federal election are big enough to where this effectively isn't going to single out anyone, they will get a few candidates from every state into the Bundestag. However the principle of forcing the gender of slot 1 just left a bit of a bad taste. Still voted for them and will most likely do that again.
