@tobie1 it's already part of the Constitution, that the Judiciary power, the the last of the three powers of the Federation will also be elected.
Mexico has been for many decades the wallet of foreign developed countries and having the court governed by appointed judges allowed to always control the ruling output.
That's the real change, it's not Claudia who is taking over, it's the México citizens ("the people") who will elect them.
I suppose that called Democracy, right?
