President Obama complained this week that his opponents "talk about me like a dog." But Dana Milbank of the Washington Post says the analogy was backward: Republicans are dogs and Democrats are cats. Milbank wrote: "Dogs travel in packs and are easily led. They communicate by snarling, growling and snapping. They tend to bark and howl all at once. They are disciplined and obey their masters. Left unsupervised for long periods, they will destroy the house. They are, in other words, Republicans. Cats, by contrast, are solitary, finicky and independent. They refuse to be herded and they hide under furniture when feeling threatened. They are not easily trained and rarely come when called. They are furtive and skittish. They are, in other words, Democrats."
