I do wonder - and I'm not alone - about that promotion. The referendum campaign would have been far too late for it.
Over here, well, these are everywhere, just part of the landscape:
When you know what paid for what because it's right up there on the sign, well, all politics is local really and "they fixed the road" is a punchline to a lot of jokes over here because every politician in the country will claim to have fixed some bit of local infrastructure. When the EU actually pays for major roads you use every day and we know that because it's on the signs.... well, like I said, 80%+ approval ratings for decades,
even as we voted against two treaties and had them reworked.
But could you have gotten that effect when instead of listing who paid for what, certain newspapers were inventing fake stories to use up excess ink about "EU standard bananas" and the like, for decades? I think this argument got lost gradually over the last 20 years rather than on one day in 2016.
