You are I take it speaking in the Past tense, at the time of the referendum.probably shows that voting leave has nothing to do with which party you support.
I suspect it had more to do with the fact that none of the parties supported the people, and took any notice of them, and so whatever the Government wanted, the people didn't, as the people wanted change, they were fed up with being ignored.
This latest vote shows that that choice made then isn't holding up, and people are voting actively against Brexit in large numbers that wanted it before they really knew what the costs might be.
No one can blame them either way.
