I was born and spent my youngest years in Teesside, a left-wing stronghold. After constantly re-electing the "pro-healthcare", "pro-schools", "pro-job-creation", "pro-community" Labour party for decades, Middlesbrough now has the shortest life expectancy in England, some of the worst exam results, an unemployment level that's twice the national average, a huge quantity of drug-related crime, high rates of teenage pregnancy and possibly the highest level of teenage prostitution in England -- again, drug-related. As far as I can see, the story is similar in other Labour heartlands like Glasgow, Merseyside and South Yorkshire.
Having seen what voting Labour for a few years does to a place, I thank my lucky stars that I live in West Sussex.
