This is a strange development, and one to keep a concerned eye on. The German state of Thuringia, which held an election October, 2019, will now have a premier from the Free Democrats (FDP), who barely cleared the 5% threshold in the election. The FDP candidate for state premier, Thomas Kemmerich, was elected by one vote over the incumbent, Bodo Ramelow, of the Left Party. With the help of the Alternative for Germany (AfD), an extreme right party, Kemmerich defeated Ramelow in a third round of voting, 45-44.
The two largest parties in the state parliament since the 2019 election are the two most extreme parties in the German party system–The Left with 29 seats, and the AfD with 22. The Christian Democrats (CDU) came third with 21, then 8 for the Social Democrats (8), and 5 each for Greens and FDP (who really did just scrape over with 5.0%). The outgoing government was Linke-SPD-Green. But they fell to 42 seats out of the 90, compared to 46 in 2014. The 2014 outcome was also a little unusual–a three-party coalition excluding the largest party (CDU, which had 34, with Left second on 28). But not as unusual as whatever government Kemmerich will put together now.
I don’t know how common a government led by the sixth largest party in parliament is, but I am guessing pretty uncommon. (Answer in comments!) Kemmerich says he will not bring the AfD into a coalition, but he now owes his position to them. What does this mean for the cordon sanitaire the establishment parties (and the Left, which really can’t be called “establishment”) have been maintaining against the far right?
UPDATE: The premier-elect has resigned, and early elections will be proposed. A decision on early elections requires a vote in the state parliament. In fact, it requires a two-thirds majority, and at this point the state’s CDU leadership has been opposed to returning to the electorate.
