Is the ghost of John Wilkes Booth to blame for the Washington Nationals' misfortunes?

It is being suggested in our nation's capital that the proximity of their stadium to the spots where John Wilkes Booth was once buried and where his co-conspirators (as well as the probably-innocent Mary Surrat) were hanged has made the Washington Nationals the victims of a curse- one even spookier than the ones put on the Red Sox by the trade of Babe Ruth to the Yankees, on the Cubs by billy goat owner Billy Sianis, or on the Blackhawks by disgruntled former coach Pete Muldoon.

While I don't believe in curses (Cub and Blackhawk fan though I am), it does make me think. The mortally wounded Booth's last words, looking at his own hands, were, "Useless. Useless." The same might, I suppose, be said of the hands of some who play for the Nats- and who, like the late Michael Jackson, wear one glove for no apparent reason.
