There’s no doubt this election is likely to see a battle to the death for both the UUP and the SDLP. Mark Durkan faces a grim battle to hang on John Hume’s old seat in Foyle. But the real story fo the election could be loss of David Trimble’s seat in Upper Bann. If he does manage to hang on in their party may have also avoided the meltdown that it’s political opponents (and some independent commentators have been predicting for it). But it’s going to be every bit as tight as the SDLP leader’s battle in Derry.
