I haven't changed my mind about the EU and would vote to leave again. However, I have changed my mind about politicians. I thought they were on the whole, humans who wanted to do good for other humans. Now I know they are worthless, self serving incompetents that don't seem to understand or care that they are affecting the lives of actual people while they play stupid one-upmanship games with each other. I suspect I'll abstain from the next general election because I can't trust any of them.
A slight majority of a statistically worthless sample size agree.
