Liberal humorist Andy Borowitz writes political satire for the "Borowitz Report," long featured by Newsweek. He's now a popular blogger on The Huffington Post and last year, his Twitter feed was honored as the world's best by Time magazine. This means that liberals really love humor that doesn't have to be funny as long as it's mean toward conservatives.
Borowitz began his Super Tuesday Republican-bashing on Twitter by linking back to his "news" feature: "Poll: Given Choice Between Romney and Santorum, Most Voters Choose Suicide." But Borowitz really hates Santorum, calling him a terrorist, an inquistor, and a mental patient (repeatedly).
