These charts reflect the results of the newest Economist / YouGov Poll -- done between November 10th and 12th of a national sample of 1,500 adults (including 1,206 registered voters). The margin of error for adults is 2.8 points, and for registered voters is 3 points.
Note that all segments of the public overwhelmingly support allowing the Dreamers (brought to this country as children and grew up here) to stay, work, and go to school in the United States. They also think the congressional Democrats agree with them.
But they do not think that Donald Trump or the congressional Republicans agree. They think they want the Dreamers deported.
Trump's attempt to overturn DACA by executive order (and deport the Dreamers) is currently before the Supreme Court. The court's decision will probably be released next June -- just before the next general election. If the court overturns DACA, that is not going to help the Republicans (or Trump) in that election.
