from Mexico City — North of the U.S.-Mexico border, Republican
presidential candidates are talking tough on illegal immigration, with
one proposing — perhaps in jest — an electrified fence to deter
migrants.

illegal immigration from Mexico is already in fast retreat, as U.S. job
shortages, tighter border enforcement and the frightening presence of
criminal gangs on the Mexican side dissuade many from making the trip.
