They are now taking Ed Miliband serious and by doing so are trying to link him to the negative side of Gordon Brown's time in office.
They are being aided and abetted by Gordon Brown 's former Special Adviser Damian McBride. Who has recently written a book describing his time as a Special Adviser.
This book has been perfectly timed to be serialised in the Daily Mail and make the Labour Party look like a party that were not united.
The media attacks on Ed Miliband has included the left wing paper The Guardian. Who are constantly trying to build a particular negative narrative about Ed Miliband.
It remains to be seen in two years time whether these attacks will have any impact on voters.
In the meantime Ed Miliband and the Labour Party need to convince floating voters in those marginal seats that they are a credible alternative.
