It depends who you ask. My guess is it's similar to red/blue in the US.

Left leaning city dwellers and corporate people often like the EU, regulations and all the socialist policies that come with it. They believe the agenda and think it's all a good thing. Maybe not perfect here or there, but better than the alternatives.

Small to medium business owners, freelancers, villagers... often hate what the EU has become. Some of them saw it earlier, some are realizing it rn. For them, it's a steady stream of super invasive nonsense regulation making their lives more complicated and expensive.

The main problem is no one has voted for most of the things the EU does. If there was a referendum about the disastrous "green politics" where people could vote if they want to pay extra carbon taxes, I don't think it would pass. Yet in some sly roundabout way all the WEF-like stuff passes again and again and again. The resistance was futile so far, but it's growing.
