UK General Election 2010 YouGov Polls Graph Election 2015: how will seven party politics work?

Apart from a slight surge for Labour during the final weekend, the biggest thing in the picture is what we called #Cleggmania, where the Lib Dem leader highhandedly knocked seven percentage points off the Tories on the night of 21 April, in the first TV debate.

And arguably at the peak of recovery, with interest rates close to zero and inflation zero, you get the Green surge (which has eased off as the election approaches).

Labour and the Conservatives have successfully made the economy the key battleground of the election.

Yet in a way, it’s the economy that is controlling them, and shaping all politics.
