What are former President Trump's immigration policy promises and how significant is immigration as an electoral issue?

Former President Trump has made immigration his top priority, promising to launch "the largest deportation program in American history" immediately upon taking office. This commitment represents one of the most aggressive immigration enforcement proposals in recent political discourse, positioning mass deportation as a cornerstone of his political platform. Immigration has become a defining issue in the current election cycle, with many of the most viral political moments centered around border policy and enforcement. The complexities surrounding U.S.-Mexico border challenges, including issues with drug cartels and ongoing border struggles, have elevated immigration from a policy debate to a pivotal electoral battleground. The upcoming elections will likely be significantly influenced by voters' positions on immigration reform, making Trump's deportation promises particularly consequential for both his campaign strategy and the broader political landscape.
