Not one for polls, but for what it's worth:
Quinnipiac Poll: Voter Support for Border Wall Hits Record HighSupport for building a wall on the U.S.-Mexico border jumped to its highest level on record, Quinnipiac University announced Tuesday, reporting results of its latest poll:
“This is the highest level of support for the wall since the independent Quinnipiac (KWIN- uh-pe-ack) University National Poll first asked the question in November 2016.â€......
Forty-three percent of voters support building the border wall, while 54% oppose it, according to the national survey of 1,147 voters, conducted Dec. 12-17, 2018.
The record 43% support represents a five-point jump from its August 15, 2018 level of 38% and is up seven points from its year-ago level of 36% (Dec. 13, 2017). Back on April 20, 2017, only 33% of voters nationwide supported building a border wall.
