BARNEY FRANK THINKS HOUSE OF CARDS IS UNREALISTIC. A reader emails: “Hey, how about a plot line where an obese, snarky congressman who always has to be the smartest guy in the room gets in trouble because his hustler boyfriend is running a gay brothel out of his apartment? Added twist, he convinces the nation that his housing bubble pop was the other party’s fault. Then there’s the time another boyfriend is busted for pot cultivation, and the world’s smartest congressman/pot legalization advocate, present when the cops show up, claims he doesn’t even know what pot looks like … Nah, no one would believe it. Memo to HOC, write in Barney, please.” Heh.
