It's interesting to see that these issues are not just an American problem. JMHO
I don't think the members of the EU realized what they were getting into, despite having only to look across the pond to see the blueprint. It was set up just like our union, with individual sovereign states that united for the common good under a limited central government. Just as ours did, the central government has slowly increased its control over the individual states. As the states have become more intertwined, they are experiencing some blowback from their collective endeavor. Italy and Greece are the front lines of the decision to absorb refugees from MENA. As countries are beginning to balk at the EU's immigration policies, Italy among them, it is bound to create friction with countries whose leaders have pushed such policies, as France's Macron has. While there is still some sovereignty for the states of the EU, it probably will be seen as a breech of protocol for an Italian official to meet with members of the gilet jaunes who intend to run for parliament. Given that voters in the UK chose Brexit over 2-1/2 years ago and their exit, and its cost, are still uncertain, I'd say screw protocol...Italy has a vested interest in seeing like-minded PMs elected from France, particularly since France is one of the two main drivers behind the insanity.
I agree. It's not much different from politicians in one state campaigning for their party in another state here.
