"I don't know what that means"

And yet, the Senate Majority Leader employed words adapted to the meanest understanding:

"Don't screw this up."

He was responding to the brash decision of the Mayor of D.C. to walk across the lawn and horn in on Sen. Reid's press conference to demand that the Senate pass the House's measure to fund D.C. during the government shutdown.  Sen. Reid walked off in a huff, leaving the Mayor and another flack to try to pour a little oil on the waters.  What did he think Reid meant by "Don't screw this up"?   He couldn't imagine.
