I know leavers and on the whole i dont think they've changed their minds.
My boss - very intelligent, but 69, of the generation that did not want to end up in the EU in the first place and has had a lifetime of being keen to get out.
MIL and FIL same age as my boss and pretty much same kind of mindset. MIL not aware of the issues and the main reason she cited to me about wanting to leave is not wanting to subsidize the Greeks Spanish and Italians. FIL said it was "very simple as we put in more money than we get back out." Boss said similar.
80 year old uncle - always opposed EU. Said we hadn't voted in 78 for the EU in its current form just for a trading relationship.
BIL - not very bright just copied my in-laws. Not sure that he's giving it much thought since but he has started going out with a Polish girl and moved her over to the UK so brexit is going to be very inconvenient for their future.
Friend aged 40, female. Intelligent. Thinks EU is just awful and wants out.
Friend aged 36, female. Not intelligent. Hoodwinked by racist propaganda. Don't know if she's changed her mind. I don't ask. The reasons she gave me for voting to leave were hair-raising. She literally said: " there's this man in London he's a rapist and a Muslim and we can't get him out because the Europeans won't let us, it's health and safety gone mad, we have to get out"!!!
Male friend, 45, knows his own mind, voted to leave because " we couldn't go on as we were could we"?
My old car park attendant he was only young (50) and he's died since. Voted to leave because he didn't want a European army.
My mum's friend in her 60's. Voted to leave because she " didn't feel British anymore" in particular cited Muslims!!
That's all the leavers I know.
