Americans by an almost 8 to 1 margin — 79 percent — think Dreamers should be allowed to remain in the country and apply for citizenship — putting most voters at odds with GOP immigration hardliners in Congress and the Trump administration, a new Quinnipiac poll said Thursday.

Another 7 percent say they should stay but not become citizens — while only 11 percent say they should get the boot.

President Trump has sent mixed signals about the fate of the Dreamers — ending the program but expressing sympathy for those protected by it — but

conservatives in Congress and his administration are dead set against citizenship for them.

American voters also oppose by 63 percent to 34 percent building a wall along the border with Mexico.

Republicans support the wall 78 to 19 percent and white voters with no college degree are divided with 47 percent supporting it and 49 percent opposed. Every other party, gender, education, age and racial group strongly opposes the wall.

“Looking at immigration, voters insist emphatically, ‘Don’t dash the dream.’ Voters say that immigrants who were brought here as kids should be allowed to live out their adult lives here as citizens,” said Tim Malloy, assistant director of the Quinnipiac University Poll.

Meanwhile, White House aide Kellyanne Conway said that President Trump “discovered” there doesn’t need to be a “physical wall” along the country’s entire southern border.

“What’s true is that after conferring with the experts who are involved in this process … the president discovered that part of it will be, he knows, part of it will be the physical wall, part of it is better technology, part of it is also fencing,” Conway said during an interview on CNN late Wednesday.

“There are rivers involved, I’m told. There are mountains involved — there’s terrain that isn’t conducive to building an actual physical structure in some places.”

The poll also showed that Americans by a 3-1 margin oppose Attorney General Jeff Sessions crackdown on pot after he reversed an Obama era policy telling federal prosecutors to take a lenient approach to legal marijuana on the state level.

“The demographics say pot is here to stay, either for fun or to provide medical comfort,” Malloy added. “And the message to Attorney General Jeff Sessions: Hands off.”
