Opinion polls conducted in 2018 reveals that 6 in 10 Americans oppose building a border wall. The Federalist offers reasons that may explain this.
Americans may become more sympathetic of immigration when public figures who want to reduce it, like Trump or Steve Bannon are on the offensive.
Some people make a distinction between building a border “wall” and a border “fence.”
The wall has become symbolic of attitudes toward immigrants and racial minorities.
Trump is a polarizing figure, particularly for Democrats.
