Norwich North and politician's logic
Politician's logic goes as follows:
Something must be done
This is something
Therefore we must do it
A little while back, something had to be done about public anger over MPs' expenses. Kicking out Ian Gibson (who, whatever his other qualities, had been using his expenses for personal enrichment) was something. Therefore we did it.
And now people are just as cross about MPs' expenses, and instead of a leftie and well respected Labour MP, we're going to have a Tory instead.
Worth remembering this fiasco next time the cry goes up that action must be taken immediately whenever the next great political excitement comes up.
