(T. S. Eliot, wearing a white rose)
One of my favorite poets, T. S. Eliot, apparently wore a white rose in his lapel to show loyalty to Richard III (whom he is supposed to have called the last legitimate English king, per this article in The New Yorker about him) and the house of York, on the anniversary of the Battle of Bosworth Field (when Richard was killed).
From this, and from the fact that the Song of Ice and Fire is (very loosely) based on the events of the Wars of the Roses, I conclude that, if he were alive today and would condescend to read science fiction or fantasy (which is probably a greater leap than bringing him back from the dead --- the man was a humongous literary snob), he would probably be a Stark fan. :)
Winter is coming!
