On July 1, Mexico will choose a new president in an election that will not only determine Mexico’s direction but will also affect the United States. For a host of reasons, what happens in and with Mexico touches more US lives daily than events in any other country. The front-runner in the presidential campaign is Andrés Manuel Lopéz Obrador, a former mayor of Mexico City who is known as AMLO. AMLO proposes to replace the “mafia of power” with a government working for the “good people.” Polls show AMLO’s lead holds across all demographics. But compared with his closest rival, AMLO has much less experience in dealing with the US. This leaves his potential management of US-Mexican relations unclear. That relationship has been tested by tariffs and tweets, and by perceptions of US unfairness in NAFTA negotiations. No matter who wins the presidential election, it is not in the interest of the US to jeopardize an important relationship. For decades, the economic well-being and security of both countries have improved when they seek “win-win” solutions. During these critical next few weeks in Mexico, the US must find ways to mend its ties with a close neighbor.
