• She is poised to become Mexico's first female president. Can she escape Amlo's shadow?

Claudia Sheinbaum seems poised to cement her historic victory as Mexico's first female president with a supermajority in congress that would let her party pass legislation and budgets unopposed - and perhaps even change the constitution without need for compromise.

Sheinbaum, a 61-year-old climate scientist and former mayor of Mexico City, won the presidency with 59.5% of the vote, according to a rapid sample count by Mexico's electoral authority.
