Biden the diplomat

U.S. Vice President Joseph Biden is meeting tomorrow with Mexico's presidential president, first with Andrés Manuel López Obrador (AMLO), then Enrique Peña Nieto, then Josefina Vázquez Mota.

Why in that order, you may ask?  From the White House,

the Vice President will also sit down with each of Mexico's three major party presidential candidates -- in alphabetical order, I might add -- to reaffirm the United States' commitment to respecting Mexico's democratic process in a totally impartial manner

Alphabetical order! Biden, the diplomat - whowoulda thunk!
