Before, we had a centre-right (CDU/CSU [the latter the Bavarian sister party]) -centre-left (SPD) government, the so-called 'great coalition'.
Now (since 1.7 million SPD-voters didn't go voting) we've a centre-right (CDU/CSU) - right (FDP) coalition.
And a left opposition (SPD, Greens, Left party).
There will be a lot of changes - or just a few, minor ones.
All depends how the new partners deal their differences.
Most certainly, the climate politic will change to a more industry-friendly politic.
Might well be that changes will also occur in health and welfare politics, plus perhaps .... but who knows?
