I love the plot summary for The Cordelia Dream, a commissioned play from Irish scribe Marina Carr that's receiving it's world premiere in London this winter with the RSC :
"A musician and his rival, a younger woman, are having a long-awaited conversation. As they spit their mutual malice with precision they question the hatred that has fuelled their desire to outdo each other in pursuit of art. With echoes of King Lear, The Cordelia Dream promises to unpick the belief that a muse must be made of love."
It's true in politics as well as art, I think. And that's why I hope that Obama will pick Hillary as his running mate.
