Months of withering political rhetoric in the presidential campaign has eroded American support for free trade but not for immigration.
The CNBC All-America Economic Survey, conducted March 21-23, finds that just 27 percent of the public agree that free trade "has helped the U.S.," compared with 43 percent who say it has hurt. Support for free trade declined 10 points since the same question was asked in an April 2015 poll by NBC News/Wall Street Journal.
"We're in a clear era where people are more likely to think that trade hurts and a lot of that probably can be attributed to the likes of Donald Trump and Bernie Sanders,'' said Jay Campbell of Hart Research Associates. The poll of 802 Americans, with a margin of error of plus or minus 3.5 percent, was conducted jointly by Hart from the Democratic side and Public Opinion Strategies from the Republican side.
