It's right in there, personalize the attacks on your opposition, attack the person, not the message, humiliate and marginalize your opponent, etc. Alinsky disciples attack individuals, not groups or agencies, because they know that individuals are more likely to break under the assault than a group or organization, like a political party. It's dirty, mean, destructive, hateful politics, but that's what 'Rats are about.
