I can't add much to the discussion about Bolsonaro but it seems to me he's getting into a nice pickle. Storm clouds are coming. Is there a possible "pretender" around? Rival in his own faction? How strong the opposition?

Found something interesting I didn't know about.
European Citizens' Initiative
https://europa.eu/citizens-initiative/home_en
Basically it's a way to influence EU legislation through grassroot movements or astroturf it if someone has the capacity, upstairs ofc I'm breddy sure they do it. Peeps can make these initiatives and can gather signatures for their cause. These can be added via a form. When they reach 1 million signatures and the threshold is reached in 7 EU countries, the initiative will be discussed by the Commission and the Parliament and maybe they make it into a law. Chances are pretty slim I would say, but not nil, possibility is open, worth trying.
Right now there's nine ongoing initiatives. What I came across was this one:
https://europa.eu/citizens-initiative/initiatives/details/2019/000007_en
It's about how national but not independent regions could get direct funding from EU and spend it any way they, like independently from their countries' policies. Here is its website:
http://www.nationalregions.eu/
And here's the form:
https://eci.ec.europa.eu/010/public/#/initiative
As of now it's largely supported by Hungarians, since it helps Székelyföld in Transylvania, maybe can be a step toward autonomy if we look at the big picture, but other regions in the EU would benefit, such as Catalonia, Wales, Frisia, or Corsica.
Now, I can't ask EU citizen Bernds to support this particular one, and share it with others and I don't. Bernd should make up his own mind if he thinks it's a good idea personally, or for his nation. Weigh if it fits into his own views.
And there are other initiatives. Maybe Bernd will find one he thinks he can get behind.
It's not a miracle switch to solve problems instantaneously, but it's a tool it can be used.
