There are now (at least) three different coalitions that could emerge after the election:
a) a centre-right coalition, led by Mrs Merkel, between the CDU, its Bavarian sister party, the CSU, and the FDP
b) a grand coalition, led by Mrs Merkel (or Schröder

), between the CDU/CSU and the SDP
c) a left-wing coalition between the SPD, the Greens and the Linkspartei (the new Left party), led by ... someone other than Gerhard Schröder.
