The Biden administration's failure to address the immigration crisis at the border was a key factor in Vice President Kamala Harris losing the election. Despite early efforts to control border arrivals, it wasn't until 2024 that significant progress was made, with a sharp decline in migrant encounters. This was attributed to a crackdown by the Mexican government and restrictive policies implemented by the Biden administration. The delayed response highlighted internal tensions and a reluctance to adopt more stringent measures earlier. Democrats are now reevaluating their approach to immigration, with calls for a more balanced strategy that prioritizes border security while upholding moral and ethical values.
