There is a rule in electoral pact-making, and pretty much any card game, which is fairly universal: don’t show your hand to the other players.
That is, don’t rule anything in and don’t rule it out. You have nothing to gain (you can fritter away your negotiation leverage when agreeing the pact) and everything to lose, in the event that you find yourself in a different situation from that expected and have to eat your words. Obvious, really. Wait until the moment comes and deal with things when you have all the information.
But it could also be argued that there one sensible exception to that rule: if the mere hint of a pact with another party could be damaging to yours even before the election. Especially when things are balanced on a knife-edge and almost anything could affect the result.
That has never really been the case with the Lib Dems: until 2010 they were a slightly dull, modestly successful and broadly respectable opposition party, whether we liked it or not. Now they are bloodied with the hard work of actual government and potentially facing a big hit at the polls, they are possibly less attractive partners. But neither are they toxic.
The same cannot necessarily be said for some other parties. Cameron would have to tread very carefully indeed in the unhappy event of ending in a coalition with UKIP, unlikely though that might seem – the toxicity of some of its members could sit ill with his (mostly) respectable party.
But worse still is the idea of a partnership between Labour and the SNP. Here’s why.
