Multiple national surveys released over the past week indicate that public support for President Donald Trump’s hard-line immigration agenda is eroding as he marks six months in his second term. A Harvard CAPS/Harris poll published on 14 July painted a fairly positive picture for the White House, with 60 % of respondents backing Trump’s push to close the southern border and 75 % endorsing the deportation of immigrants with criminal records. Just over half, 52 %, said the administration’s enforcement efforts were about right. Subsequent polls, however, point to a sharp shift. A Quinnipiac University survey conducted from 10-14 July found that 55 % of voters now disapprove of Trump’s immigration policies, compared with 40 % who approve. Only 38 % supported his handling of deportations, and 64 % opposed sending migrants to third countries. An AP-NORC poll released on 17 July measured approval of Trump’s immigration performance at 43 %, down six percentage points since March. A CBS News poll published 20 July put the president’s overall job approval at 42 % and reported falling support for his expanded deportation programme, findings echoed by a CNN/SSRS survey in which 55 % said the crackdown had gone too far and 57 % rejected the construction of large new detention facilities. The accumulating data suggest the president’s signature issue, once a reliable source of voter enthusiasm, is becoming a liability as disapproval of both his immigration agenda and broader performance reaches its highest level of the current term.
