Poll: Six in 10 disapprove of Trump's declaration of a national emergency

Nearly 6-in-10 also don’t believe there is an emergency at the southern border and that the president is misusing his presidential authority. They also believe that his decision should be challenged in court.

“All things related to the declaring of a national emergency, the president is striking out in the court of public opinion,” said Lee Miringoff, director of the Marist Institute for Public Opinion, which conducted the survey. “He’s maintaining his base and little else.”

Republicans and Trump supporters are firmly with the president, while Democrats and independents disapprove. These numbers slightly outpace, but are largely reflective of, the president’s overall approval rating.
