Here's some useful advice from an old country saying: Never try to teach table manners to a pig — it doesn't work, it'll wear you out, and it just annoys the pig.

The same advice goes for anyone who thinks they can teach even a bit of common sense to the preening political ideologues who've taken over the Republican Party and the U.S. House of Representatives. As we've seen in their incessant, pigheaded attacks on the health care reform law, their minds are not merely fogged up with extremist anti-government theories, they're impervious to rational thought.

They failed to defeat Obamacare in 2010, despite trying to scare old people with mindless lies about "death panels." Now they're trying to repeal the law by getting people to swallow their hogwash that it contains "a massive tax hike on the middle class."
