One way Mexico may try to indicate their displeasure with our current administration is to buy fewer products from the US. One large US export, corn, goes predominantly to that country, and though it's not as easy as they would like to find another supplier that can produce as much as we can here in the US, a significant cut in their imports could adversely affect the price of US corn, and hurt farmers' pocketbooks. Since these farmers are living on a fairly thin margin, with costs up and revenue down over the past few years, a drop in prices could really hit agriculture where it hurts. Otherwise, the prognosis is for corn prices to stay about the same in the short run, at least.
