Grocery prices might not be rising as quickly as in previous years, but they were still a major factor in getting people to the polls during this month’s elections. According to A.P. VoteCast, 96 percent of those surveyed considered high prices for gas, groceries, and other goods when they voted.

But the centerpiece of President-elect Donald Trump’s immigration policy—his proposal to deport millions of undocumented immigrants—could badly disrupt the country’s food supply and raise grocery costs, given the share of farmworkers and food workers who are undocumented. That possibility is a reminder of how urgently the U.S. needs to reform its agricultural visas and related pathways.
