Security & Strategic Review - April 2026

Mexico’s President Claudia Sheinbaum began an electoral reform drive on 4 March, submitting a 10-point constitutional reform bill to congress. This was rejected after failing to garner the support of the ruling party’s typically dependable congressional allies. Seemingly unfazed by this, Sheinbaum presented a ‘Plan B’ reform on 12 March – the day after the lower chamber rejected her original proposal. In this second bill, what was initially an ambitious restructuring of the political system narrowed into a more calculated and politically viable initiative, but one that still carries significant consequences for the balance of power ahead of the 2027 mid-term elections.
