Somewhat surprisingly, FDP voters are in the lead with 88%. CDU/CSU voters follow with 81%, 69% of Left party and 68% of Green voters follow, and 'a majority' of SPD voters are last.
On the other hand, regarding my nightmare scenario, in another poll a mere 25% would support repeated elections and 73% oppose, I guess that wouldn't bode well for the CDU/CSU if they pursue a new elections tactic too openly.
As mentioned in other threads, 33% would favor a Grand Coalition, 26% a 'Jamaica coalition' with Greens, FDP and CDU/CSU, less than 20% favore an 'Ampelcoalition' with SPD, Greens and FDP, and a mere 9% a red-red-green coalition.
In there is a Grand Coalition, half want Schröder as chancellor, only 43% want Merkel. *Lunatic*, n. One whose delusions are out of fashion.
