> While they might not know the precise details, they know that a "Constitution for Europe" was rejected by French and Dutch voters in 2005, it was changed into a "Reform Treaty" in 2007 which meant most countries' voters didn't get a vote on it, and after Irish voters rejected that, they had to have a second referendum on the same treaty the year after.
But that's fine isn't it? After all, if we didn't get a 'Constitution for Europe' (which I'm ambivalent about) the treaty got us most of the benefits and as far as I can see today none of the drawbacks. Those drawbacks that were mentioned did not materialize, which seems to be the case with most EU law: there is an enormous amount of racket about how it will cause problems down the line but that almost never happens.
> They feel they have seen how EU law interacts with local law, and they don't like it.
Given how EU law has kept dutch politicians in line during the last decade or two I'm pretty happy with it. Without EU law NL would arguably in much worse shape re. international trade, privacy, anti-trust, agriculture, climate commitments and a whole bunch of other subjects.
Of course if you're a climate denier or you want to return back to the guilder none of those arguments matter but in general I see far more positives then negatives. Those local politicians that are clamoring the hardest for splitting from the EU bear the most scrutiny: likely their agenda requires a lack of oversight to succeed.
