U.S. business along the U.S.-Mexican border are watching the Mexican presidential election campaign closely, for its influence on border economics.

Businesspeople north of the border say they want to see a president who will bring a business sense and one who can continue working to quell Mexico's drug violence. That is as important as any other factor in helping drive business across the border, they say.

In one irony, a Brownsville, Texas, businessman says, the return to power of the Institutional Revolutionary Party to the presidency could reduce the violence.

"If Mexico goes back to its old ways as far as corruption -- government powers taking bribes to let the drugs go freely -- in a sense, that will cut the violence," says Daniel Hong, who runs a general goods store just minutes from the border in Brownsville.

Enrique Peña Nieto, the Institutional Revolutionary party candidate, is currently the favorite to win the July 1 balloting for what will be a single, six-year term.
