Germany's third parties fight over the scraps ahead of Sunday's election Struggling to retain their historic kingmaker and coalition partner role in this election, the FDP Liberals face polling less than five percent and missing out on parliamentary representation. That would let the left in, warns its leader. The alternative to our black-yellow coalition is a red-red-green one. Please imagine an SPD/Green/left party government with Sigmar Gabriel as leader, Juergen Trittin as finance minister and Gregor Gysi as foreign minister. Ladies and gentlemen, this cannot happen," said Rainer Bruederle at one of the party's last rallies. The Greens are struggling, too, and face dropping below 10%. This would lessen their influence in any left-of-centre coalition, and force their allies of choice, the SPD, into a grudging three-way marriage with the more leftwing Die Linke party. Bolstered by growing support going beyond its East German strongholds Die Linke has a sniff of gaining a share of power for the first time since Germany was reunited. If you want the SPD to become social-democrat again there is just one way: you need to vote Die Linke. I am sorry, this is the only thing that can educate them," insisted Gregor Gysi. Any one or a combination of these parties could prove vital if no overall winner emerges on Sunday, and a coalition needs to be built, something the opinion polls suggest is more than likely.
