Are you seriously saying that it wasn't up to labour to campagn to stay in because the tories called the election?
Point is a bit moot though. They both campaigned. As well as other parties.
The Tory councillors stopped to talk to me, I did some digging after, the MP lived the other side of the bloody city, in a very nice big area. They didn't know the area at all. One just kept going on about how Jeremy corbyn is a career politician and got disgruntled when I pointed out TM has been in the job 20+ years and by his own logic, that'd make her a career politician too.
