There is evidence that the Republican Party’s rank-and-file electorate has always had a populist, anti-free trade streak and that the GOP Party bosses have long been trying to force something on them that they didn’t want. A prime example was the insurgent candidacy of former Reagan adviser Pat Buchanan in 1992 that left President George H.W. Bush hobbled coming out of the primary election opening the door for a Bill Clinton surge.
