According to Merriam-Webster online, a "straw man" is "a weak or imaginary opposition (as an argument or adversary) set up only to be easily confuted."

needs to attack the snobs who are savaging Sarah Palin’s faith and family. Many liberals claim to love working-class families, but the moment they glimpse a hunter with an uneven college record, they hop on chairs and call for disinfectant.

Can anyone--anyone?--please point to one "liberal" commentator who acts that way? I mean, anyone since NEW YORKER film critic Pauline Kael said in 1972 that "I don't know how Richard Nixon could have won. I don't know anybody who voted for him."
