There is no comma between the penultimate item in a list and "and"/"or," unless required to prevent ambiguity.
The serial comma—also known as the Oxford comma—is the comma often needed before the conjunction at the end of a list.
When you omit the serial comma—as Rudy has—you kill the meaning of your statement.
You might argue Rudy saved a stroke.
But he induced a stroke among his followers, by pitting the party of Reagan, Trump and the traitors (whoever they are) against that of Lincoln.
A single comma would have been the life-saver.
While Rudy's sin of omission is exquisite, my all-time favorite remains this book-dedication by a fellow right-winger:
This book is dedicated to my parents, Ayn Rand and God.
Although you might think so, the book's author wasn't Mike Lindell.
The author merely shared similar parentage.
