Will warnings of chaos affect the electorate?

Ken Clarke delivered the IMF warning today at the Tory press conference. Clarke, a politician experienced enough to remember the last time no party had a majority in the Commons and the last time the IMF was called in, said that if the electorate did not put in a government with a working majority that is serious about dealing with the debt and the deficit then the IMF will do it for us. He scolded the electorate, saying that ‘not every single member of the electorate seems to realise how serious this election is.’  

The Tories hope that this bucket of cold water will help end voters’ infatuation with Nick Clegg and the Liberal Democrats. My worry is that the electorate actually wants to bring everything tumbling down so warnings of chaos will have little impact on them The Tories are relying on the reality of what massively higher interest rates would mean kicking in at some point before polling day.
