The construction of a border wall is a highly partisan issue. The Republican platform explicitly endorses the construction of a wall along the Southern border, while the Democratic platform expresses harsh opposition to the concept. Polling reflects a similar partisan divide; 82% of Republican voters favor the construction of a Southern border wall, while 93% of Democratic voters are opposed.
In December 2018, House Republicans approved a bill to fund President Trump’s border wall. It passed 217-185, with eight Republicans voting against the government funding package that included $5.7 billion to construct a border wall. The bill received no Democratic support.
