I voted Labour minority in your poll, but a perhaps more likely scenario is a Lab-LD minority coalition. They will still need SNP votes to survive, but at least a Lab-LD coalition will command more seats than the Tories, thus giving them more credibility, and they will also win votes when the SNP abstain (which they will do on any England-only measure.) It will therefore be in Labour's interests to seek this coalition, if the election result goes as predicted.
Ive wondered about this too. forgive my ignorance, but why wouldn't the LDs be inclined to join an anti-Tory coalition? i realize they're not necessarily friends of Labor, and their top priority would be which party offers them offers them more influence/power in a government plus the chance to kill FPTP, but why does everyone seem to think an alliance with the Tories is the more likely outcome?
