The trumpoisie are the 25-year locusts of American politics.

If these voters are be­gin­ning to sound fa­mil­i­ar, they should: War­ren’s Middle American Radicals of the 1970s are the Don­ald Trump sup­port­ers of today. Since at least the late 1960s, these voters have peri­od­ic­ally co­alesced to be­come a force in pres­id­en­tial polit­ics, just as they did this past sum­mer. In 1968 and 1972, they were at the heart of George Wal­lace’s pres­id­en­tial cam­paigns; in 1992 and 1996, many of them backed H. Ross Perot or Pat Buchanan. Over the years, some of their is­sues have changed—il­leg­al im­mig­ra­tion has re­placed ex­pli­citly ra­cist ap­peals—and many of these voters now have ju­ni­or-col­lege de­grees and are as likely to hold white-col­lar as blue-col­lar jobs. But the ba­sic MARS world­view that War­ren out­lined has re­mained sur­pris­ingly in­tact from the 1970s through the present.
