MEXICO CITY (AP) — Mexico’s leading presidential candidate repeatedly touted the social programs of outgoing President Andrés Manuel López Obrador and walked a fine line between supporting the national oil company and promising a clean energy transition in the second debate Sunday night ahead of the June 2 election.

Former Mexico City Mayor Claudia Sheinbaum of the president’s Morena party continues to hold a healthy lead over Xóchitl Gálvez of a coalition of opposition of parties and Jorge Álvarez Máynez of the small Citizen Movement party.

López Obrador significantly raised Mexico’s minimum wage and increased spending on social programs, most of which are popular direct cash transfer programs. Sheinbaum has benefitted from her mentor’s popularity throughout the campaign and promised to continue his programs.

She called the model of government that he started and she has committed to continuing “humanist, an honest model, protector of our patrimony, with better salaries, with better pensions, without raising taxes.”
