Alan's right. This comes down to how effective/toothless the MP is. Whatever your take, Bradley's legacy includes new schools, health centres, etc. Leech has signed 1013 EDMs. No comparison.
Let's go to the polls. Half the country might vote. Brown'll get in on a slightly increased majority. And it'll all be done nicely in time for John to be able to concentrate again on one job, as a councillor. Where his *talents* are best suited.
