Mexico is not sending their worst; their worst are the ones who stay to run their country
Mexicans cross the river and climb over the border walls because their corrupt elites have impoverished them, left them with no other option than to migrate to America. That is the truth the Donald Trump should be shouting out, but he won't, because he himself is very much like those uneducated and corrupted elites of Mexico.
Under Donald Trump America will officially have a president with less qualifications and brais than those required to run any Latin American country.
