No , of course not everyone of the 52% based their vote on immigration or race etc, and I don't think anyone has said that have they? But some people did, what that % is can't be measured, as few people admit to it. But there was plenty of focus on immigration in the campaign. I did hear people say the"didn't mind the Polish, but didn't like Muslims" as their reason for voting leave, and several jibes at Polish shops etc. don't need to go over all that again,But everyone agrees that reason for voting either way are varied as Petra, her friend and everyone else must know.
