Excellent PR stunt from David Cameron. Just before election put the idea in the electorate's mind that he's already won it. Genius.
I know why David Cameron made his 'third term' comment. He's managed to keep all the headlines and news feeds away from discussing the damning revelations from last night's Channel 4 Dispatches program.
Government ministers can deny it all campaign long if they wish, but Cameron's revelation has dealt a mortal blow to his leadership. Lose the election - he has to go. Win the election but fail to renegotiate with the EU - he has to go. Renegotiate, but lose a referendum - he has to go. Even in the unlikely event he manages all 3 - he's going anyway!
