- The Green party would definitely come back to try again. It was such a part of the way society was moving that it is not that easily to butterfly away at that point of time.
- The CDU/CSU alone would not be in the position to change the voting system towards a majority system. They need a 2/3- majority and the SPD would, despite the possibility to kill off the Greens once and for all, not got for that as it would be the way to turn Germany into a big Bavaria, electionwise.
- The FDP might become part of the coalition, still. First of all, as a reward for treason, and secondly, to keep FJS in Munich. Kohl would have hated to have this guy as foreign secretary.
- However, there is a good probability that, in the coalition or out of it, the FDP might not recover from this. They took quite a ditch OTL and since then their voter base is always a) very fragile and b) dependant on strategic voters who actually are sympathetic to the CDU.
- It is really probable that Kohl might defend this majority in 1987, especially if voters write the FDP off.
- Now an absolute CDU majority 1983-90, that might change Germany a bit and have butterflies, but still, I do not see epochal changes. Maybe a bit more corruption.

1. Agreed
2. No, you don´t need a 2/3 majority. The electoral system is no part of the Basic Law, it can be changed by simple majority. The reasons that it wasn´t changed were always pure political. In the fifties the Union had a absolut majority in the Bundestag, but the FDP threated to bring down all CDU-Ländergoverments, if they tried to change the electoral system. In the sixties everybody expected that a FPP-system would favor the Union and so there wasn´t even a simple maority possible. But ITTL the Union would have absolut majority in the Bundestag and in 5 Ländern, given them also an absolut majority in the Bundesrat. (There was only a CDU/FDP coalition in the Saarland at this time)
3. At this time, the FDP had already established, that they would never form a coalition with a party which had a absolut maority. Okay, such promises can nbe brocken but in this case it would propably just speed the decay of the FDP. It seems that Kohl in 1982/83 actually put real afford in it to convince Strauß to oin the goverment as minister of finance or defense. He wanted to have Strauß in Bonn to better control him. Its possible that Strauß always declared that he wanted to become foreign minister, because he could be sure that Genscher wouldn´t never accept this (Better the first in Munich, but the second in Bonn)
4. Agreed
5. Agreed
6. A absolut conservative majority in Bonn makes Andropov much more paronid, Able Archer leads to WWIII AND WE ALL DIE! Changes enough?

Okay, just a joke. Okay, maybe not such epochal changes, but I think its possible the whole
geistig-moralische Wende-thing would play a creater role ITTL. IOTL Kohl could always play out the FDP against the conservatives in the Union, but with a comfortable absolut majority I think its possible that the conservatives would demand a stricter abortion law.
And if it comes to a two-party system (or at least a system where the to big party don´t really need the other partys anymore) the Union-dominance could last till 1998, followed by a SPD-dominance which last till 2009 or beyond.
