and don't forget:I don't see any further candidate on the 2nd ballot than the three aleady there, Hindenburg, Marx and Thälmann.
The swing needed wasn't so large, just about 2% of the voters, about 700k to 800k to get even though a very close win for Marx.
- The BVP option I've mentioned already above, admitted : difficult due to 'strained relations' between the two sisters Center and BVP. But maybe a horse-trading could have helped. The ministry for Postal Affairs they got already. Bavaria in that time had always issues with the Reich regarding payments from the Post to Bavaria. Maybe some additional 'rights' for Bavaria in that respect. As an addition maybe the Ministry for nutrition and agriculture, which was 'free' (of a party-member minister) at that moment. Should be interesting for mainly agrarian Bavaria.
- The DVP option ... I skip after having read this link provided by @David T . But this also showed me the possibility of
- A DDP-option. The DDP might be pisssed enough by the rejection of 'their' candidate Otto Geßler to be convinced to run again with the democrats, the 'old Weimer coalition'. OTL they - the party officials - finally went with Hindenburg.
- Maybe a combination of the BVP and DDP options
- Hindenburg says no (AFAIK he was reluctant IOTL) and te right wing put forward a less popular candidate.
