A new Pew Research Center survey finds that majority of Americans (58%) continue to oppose substantially expanding the border wall, while 40% favor the proposal. Overall opinion on the wall is little changed from last year, but these views have never been more sharply divided along partisan lines: Republican support for the wall is at record high, while Democratic support has reached a new low.

And both sides appear to be dug in: Nearly nine-in-ten (88%) opponents of expanding the border wall say it would not be acceptable to pass a bill that includes President Donald Trump’s request for wall funding, if that is the only way to end the shutdown. Among the smaller group of wall supporters, 72% say a bill to end the shutdown would be unacceptable if it does not include Trump’s funding request.
