So if you're working class you have to vote Labour and if your middle class you have to vote Tory....that's ridiculous, you should vote for party that you believe in the most. Your background or social status should have no relevance.
Its a throw back, its traditionally what the parties stood for, but as we are generally a small c conservative country when JC was elected the tories grabbed the center.
Whats happening now has been happening since the end of the Blair/Brown years, a lot of the middle class voted for Labour because they actually wanted to look after the working class, Labour pandered more to the Middle class and ignored the working class's issues and just assumed they would automatically vote for them.
So much so that instead of looking inwards and looking at the rhetoric used, the vocal support became full of people like Bertrand who scoffs at the idea at why they are not thinking like them, they where happy with the "racist" UKIP voters when they voted for Labour and kept quite, but they cannot fathom "but why", despite many of the working class telling them, after the "but its the Tories!!" it becomes akin to union scab mentality.
Basically Labour banked on these people, they weren't listened to (hence a partial reason for brexit), and, in the case of Wales, are sick of being told that after being a labour stronghold it is still Thatchers fault.
the old saying goes, the right looks for converts while the left look for traitors
The last part is evident in this thread and will be evident for the next couple of weeks
