Will the tactical voting plea work?
There's only one question which matters when it comes to Labour's tactical voting plea: will it work? You can certainly see Brown & Co's thinking on this. This is the election, after all, where the Lib Dems have become a viable option for a lot more people - so they might act as a speed bump for people rushing away from Labour and towards the Tories. And anything which depresses the Tory vote gives Labour a greater chance of holding the most seats in the House, and of making some kind of post-election pact with Nick Clegg. But as David said earlier, Labour's osciallating stance towards the Lib Dems - lofty sneers one minute, sickly grins the next - is hardly convincing. And neither is the timing.
