Towards the end of last week I had a long conversation with a Conservative activist who has been canvassing in key target seats in the southeast.
He had been working in the Dagenham and Rainham parliamentary constituency mostly focussing former council estates which at past elections have been pretty solid for Labour. What was striking, he told me, was the massive negative reaction to Jeremy Corbyn that he was getting on the doorstep and how quite a few of those being canvassed wanted to use the conversation to vent the anger with the Labour leader.

to be fair, D&R went 40/34 Labour in 2010 and nearly gave UKIP 30% in 2015. I'd think that seat flips easy in a landslide
