Its his only hope of winning.

Then he will treat all of the voters like this:
Ken Livingstone was stand at the pearly gates, when St Peter asked him what good and bad things he had done in his life. To which he replied as a politician I've always tried to help people, but at the same time I've been bad by being hypercritical on tax, private medicine and many other things. St Peter replied that he wasn't sure whether to send him to heaven or to hell, so he would let Ken decide after spending a day in each.
On his day in heaven he floated around on a cloud, bumped into all sorts of nice people who were all very friendly towards him.
The next day in hell to his surprise he found a green and agreeable place. In no time he had met up with all of his socialist friends, they had a round of golf together and then went for a good meal.
The next day in front of St Peter, he was asked where he would prefer to go. He replied, this must sound strange but although heaven was very nice, it was how could he put, boring compared to the day he had had in hell with his friends, so he would rather go to hell.
St Peter accompanied him on the long trip down in the lift and as soon as the door opened, kicked him into hell. The devil immediately applied some arm and leg irons and kicked him into a fiery pit. Through the agony of the fire and brimstone, Ken shouted to the devil, what has happened? It wasn't like this yesterday. To which the devil replied, yesterday I was electioneering, today I've got your vote.
