Reasons for preferring the present Labour Party over the Tories are getting fewer and fewer.

It's still possible to argue that the Labour Party out in the country is often a lot nicer than the Front Bench, and that the Tory Party is often a lot nastier than its Front Bench. But the possibility of the decent parts of the Labour Party taking back control are probably even slimmer while they stay in power than if they get chucked out.

The best hope may be that a hung parliament results in electoral reform that will enable a new party lineup to develop, so we can vote the way we prefer, rather than just trying to keep out whichever bunch of politicians looks the most unpleasant.
