SAN FRANCISCO DEL RINCON, Mexico - Former Mexican President Vicente Fox says a Donald Trump presidency could lead Mexico and the U.S. to a trade war that would hurt both countries.

A day after Trump stretched his lead over GOP rivals with wins in Michigan, Mississippi and Hawaii, Fox says that if he were to impose tariffs Mexico would have to react in kind.

Fox says "we are going to lose everything in a trade war."

He added Wednesday that it's up to Hillary Clinton to "save" the United States from a Trump presidency.

Fox also criticized Bernie Sanders as a proponent of the kind of "stupid" populism that has led to "demagogy" in some Latin American nations.

Nor does he like Ted Cruz and Marco Rubio, who Fox said "denied their (Latino) origins."
