On Monday 30th March 2015, the current UK parliament will be dissolved.
Five and a half weeks later, on Thursday 7th May, there will be a General Election to decide a new one. This is not prophecy, this is the Fixed Terms Parliament Act of 2011, which has decreed, for the first time, that we know these dates far in advance.
But what happens after 7th May is much harder to predict.
Can social data allow us any foresight?
