The SNP will soon have to face the reality of a simple choice.
Either they vote in support of Labour without getting a bean in return, we have conservative government or we have another election.
If only it were that simple, David "cowardly" Cameron is now saying that he'll squat in Downing Street unless Labour have more seats than the Tories, on the grounds that the party that finishes second forming government wouldn't be legitimate and therefore couldn't command the confidence of parliament. If he wins that argument and the polls are correct then it's either a Conservative government or another election
