Is it time for them to consider tactical voting? Mike Smithson over at PoliticalBetting.com has made the case for this before, if you want to get rid of this government, vote for the party best placed to beat New Labour in your constituency. In Scotland that seems to have happened already, the business community has switched from the no-hope Tories to the SNP. In return the SNP has begun to talk more about “Enterprise Scotland” and is now polling even stronger than during the recent local elections.
The problem is that LibDem and Tory activists hate each other. They would not countenance any explicit instruction to vote for the other party. Often at each others neck in local government, the idea of a non-aggression pact is unpalatable. Rather than going into any protracted negotiations the Tories should just direct resources away from LibDem incumbents and into the battle in Labour seats. The LibDems political antennae would detect the shift, they would consequently be able to shift their more limited resources away from defending LibDem seats against Tory insurgents and towards attacking Labour incumbents.
