Day 1 Semantic analysis of the UK general election

This is the first daily semantic wall about three political leaders David Cameron, Conservative; Gordon Brown, Labour and Nick Clegg, LibDem.
The methodology being used is described in this post.
You are invited to comment and criticise as much as you like :)
This is not a full 24 hours so we can expect the returns to vary over a few days.

What is most interesting is that this is already showing major differences. I am curious to know what happened to Gordon Brown in his own analysis?
