Lopez Obrador - popularly known as AMLO - published a book a year ago that was sharply critical of Trump, fueling concern he might prove more combative with Mexico's largest trading partner. He conceded defeat in a televised speech. Failure, though, will probably further destabilize not just his nation but also ours, exacerbating tension over immigration and undermining trade.
"I will not rule out any option" to achieve peace, he said at a recent debate.
Since 1929, the Mexican leader has been from one of two parties: the PAN or the PRI.
Lopez Obrador, who has run for president in every election since 2006, has humble beginnings, flies coach class and says that he will convert Mexico's presidential palace into a public park.
At one point, Lopez Obrador's Jetta, which often snaked through Mexico City with the windows down, knocked a member of the posse off his motorcycle while making a right turn. Newspaper El Financiero's exit poll gave him 49 percent of the vote to 27 percent for Anaya and 18 percent for Meade.
Mexican business group Coparmex called previous year for the creation of a strongly independent body to counter the tendency of Congress to approve expansive budgets.
The leftist Lopez Obrador won a landslide victory on Sunday, besting a four-candidate field with more than 53 percent of the vote in preliminary results.
"More broadly, Mexico has been governed by a centre-right technocratic elite since 1982".
O'Grady added that she believes Lopez Obrador is going to be "very careful" at first, due to Mexico's exposure in the global market.
This is the first presidential election for Lopez Obrador's party, the National Regeneration Movement (MORENA), which has formed a coalition with the left-wing Labor Party and right-wing Social Encounter Party. The influential Mexican business community started to push heavily for a more open economy and put their support behind pro-US politicians.
Three political party members were shot dead on election day, according to local officials: a Workers' Party (PT) member in the western state of Michoacan, and two members of the ruling Institutional Revolutionary Party (PRI) in the central state of Puebla.
This conciliatory tone and talk about "reaching an understanding" with the U.S. after the election is not what many of his voters want to see.
"If they do, we're going to be living in a dictatorship", Felix said in the report.
Carlos Cardenas, head of Latin America country risk calls it "unlikely" that Lopez Obrador would "conduct a wave of expropriations/nationalisations across all economic sectors".
The idea of an amnesty has divided voters, with a poll this year showing that more than 7 in 10 Mexicans rejected it.
It seemed Lopez Obrador wanted the team there to protect him against the crush of adoring crowds or attempts to politically embarrass him, for example, by paying someone to confront him verbally. In his quest to please his support base, President Trump will surely still insist on building a wall, persisting in his claims that Mexico will pay for it.
People cast their vote during the presidential election on a polling station in Xochimilco, Mexico City on July 1, 2018.
President Donald Trumpsaid Monday he has had a 30-minute phone call with the newly-elected leader of Mexico, Andres Manuel Lopez Obrador, discussing trade, border security, the North American Free Trade Agreement (NAFTA) and the possibility of a Mexico-U.S. trade deal.
This worries some Mexicans, who see Lopez Obrador as unpredictable, prone to outbursts of emotion and quick to change his mind on issues.
