Generally, blaming all bad things on the EU and acting like it's a foreign power whenever it servers their needs, obfuscating the the national governments are the ones with most power over EU decisions.
I reckon this was a major reason Brexit went the way it did. Supporters of the EU liked to point to the fact that actually, our government was behind a lot of the unpopular EU actions to argue that Brexit supporters had been tricked into wanting to leave the EU. What they didn't get was how completely unconvincing an argument that is. The politicians who were busy undermining and blocking any attempt to leave the EU also used it as a way to pass laws that the people they represent didn't want, shielding themselves from any kind of accountability to the general populace, and that was meant to make everyone fall in line behind them and want to remain in the EU? Ridiculous.
