Agnew also was a de facto beta test for Trump, with incorrigible racism (calling Polish-Americans “Pollacks” and a Japanese-American reporter a “fat Jap”), personal attacks on DOJ employees, serial lying, pitting rural Southerners against city dwellers (“When you’ve seen one slum, you’ve seen them all”), and implicitly anti-Semitic rants about the press.
I shudder to think of the petty, vindictive revenge Agnew would’ve pursued, had he inherited the presidency from Nixon.
If Trump isn’t truly sui generis, then Agnew was the stuffing-pockets-with-cash Id from which he was molded.
