From the Pew Research Center:
About two-thirds of Republicans and Republican-leaning registered voters (68%) say free trade has been a bad thing for the U.S., while only 24% say it has been good for the country. These views, which have shifted starkly since May 2015, when 51% of Republican voters said free trade was a good thing for the U.S. and 39% said it was bad, came as President-elect Trump criticized free trade throughout the 2016 election cycle. Democrats, on the other hand, remain largely positive about free trade.
