At PolitiFact, we have been fact-checking statements at least since 2013 about majority support for gun background checks, and have found them to be generally accurate, although support is typically lower than 90% among Republicans. The National Rifle Association has previously pointed to the results of background check voter referendums in Maine and Nevada in 2016 that showed lower support for background checks than the national polls suggest. Pew Research Center found in 2013 that 81% of Republicans supported expanded background checks, but when asked if they supported a U.S. Senate bill that included such legislation, Republican support dropped to 57%.
