As a Republican president prepares to exit, so does Opus cartoonist Berkeley Breathed -- again. The Pulitzer Prize-winning creator of the '80s super-strip Bloom County, which wrapped up shortly after President Ronald Reagan's second term, announced Monday that he will end his Sunday-only strip, Opus, on Nov. 2 -- as in, two days before the presidential election, reports Michael Cavna, who writes the blog Comic Riffs on washingtonpost.com.
