The frequency with which American politicians—and Republican ones in particular—habitually neglect or pass up obvious chances to score a telling hit on their opponents is really amazing.

An immediately recent example is the claim made on the campaign  trail by Andrés Manuel López Obrador, the leading candidate for the Mexican presidency in the forthcoming election on July the first, that immigration to the United States is “a human right” for all North Americans and the promise that “soon, very soon—after the victory of our movement—we will defend all the migrants on the American continent and all the migrants in the world” and urge them “to leave their towns and find a life in the United States.” This remarkable statement, assuming that President Trump or someone on his staff noticed it (as how could one of them not, even though the New York Times did not include the incident in “All the News That’s Fit to Print”), gave Mr. Trump the perfect opportunity to claim that the so-called “immigration crisis” is actually  a crisis point in the invasion of the United States by the Third World countries south of its border. So why were Obrador’s words ignored, and the opportunity to make political hay from them overlooked?

An interesting, incidental, question is why Señor Obrador views the United States as the country of natural right for all the peoples of the world. Is it because the U.S. is simply the Best Place? If so, the implication is that the hated gringos, who built the Best Place, are also the Best People, and should be looked up to and respected as such by societies around the world.
