http://usparks.about.com/od/conservationpreservation/a/National-Christmas-Tree.htmIn 1978, a 40-foot-tall living Colorado blue spruce was donated by an anonymous family in Maryland, was transplanted to the Ellipse where it continues to serve as the National Christmas Tree ever since.
The Governor of Maryland is Democrat Martin S. O'Malley and is represented in Congress mostly by Democrats, including the socialist progressive Steney Hoyer, who recently voted in support of the removal of DADT. Additionally, negroes make up more than 33% of the population of Maryland.
Said tree is obviously spreading black socialist cooties all over Washington.
