Mexico’s Sheinbaum tells US: Don’t use Mexico in midterm elections

Sheinbaum's pushback lands at a moment when bilateral friction over anti-drug cooperation is being folded into US domestic politics, which raises the risk that enforcement and security files get negotiated through an electoral lens rather than a technical one. For markets tied to Mexico's cross-border trade and security-linked investment, the signal is that diplomatic noise is now a recurring variable, not a one-off. The open question is whether this friction stays rhetorical or starts touching cooperation that supply chains and investors depend on.
