Bloomberg gives their spin about why Poland is being punished using article 7.
The fact is that Poland took down corrupt judges (read EU shills) and made them subject to the same laws as normal people.
The EU is frightened that other countries might do the same thing and start holding officials accountable. This would quickly destroy the EU as opposed to watching it collapse under its own weight.
The spin is that judges are being made into political pawns of the right, as opposed to political pawns of the left. And that this will end life on earth.
The EU is simply scared. It's fighting for its life. But it's too late. Stick a fork in it. It's done.
