Sheinbaum's power stays decoupled from her polls: even as at least one major tracker keeps her below 50%, the reconstituted Supreme Court (Morena-aligned since it was seated in 2025) reverses no signature Sheinbaum/Morena federal law on the merits, and no surviving autonomous regulator blocks a flagship policy, through the end of 2026.
Strongest counter — A newly elected court sometimes flexes independence early to build legitimacy, and a handful of elected justices have signaled autonomy. It survives as a banger because a 5-of-9 aligned majority plus a Morena/Senate-controlled candidate-selection filter makes a merits reversal of a flagship law inside 15 months a low-probability event; the claim is about signature laws, not every ruling.
Wrong if — the Supreme Court (SCJN) invalidates any federal law enacted under Sheinbaum on the merits, or a surviving autonomous body formally blocks a flagship federal policy, before 2027-01-01.
