Tom Wolfe, Evelyn Waugh, Tom Sharpe, Mickey Spillane, Jorge Luis Borges, and Gabriel Cabrera Infante are/were all men of the Right. Even Balzac can be considered a Paleoconservative in the French context.
I hate Borges! Just kidding. Spillane eh? Well I meant good novelists. :-)
Most BORING leftist writer: John Steinbeck. I wanted to throw up after reading Grapes of Wrath.
