In 1950 Stetson Kennedy put himself up as a write-in candidate against Florida U.S. Senator George Smathers who had so notoriously defeated Claude "Red" Pepper in the Democrat Party primary for that office. The above is Woody Guthrie's song for the Kennedy write-in campaign and echoes much of Pepper's equally notorious counter-mudslinging against Smathers in the earlier election.
The "Dupont" actually references Smather's law firm major client, Edward Ball, executor of the Alfred I. duPont Testamentary Trust and pres. of the St. Joe Company; Henry Flagler's old railroad and hotel interests and countless other Florida & Bahama investments in sugar, lumber, railroads, real estate &c.
