I'm trying to clarify for you that your point is a) wrongheaded and b) overwrought.
If the Bush White House decides that there isn't going to be a political demonstration on the White House lawn at their expense, there isn't going to be one. They can handle it, and they needn't dash any kids' hopes unfairly and on-the-spot, producing the lugubrious video footage you seem to anticipate -- and the MSM, too, no doubt, and no doubt they are drooling at the potential:
GEORGE W. BUSH, CHILD HATER
FILM AT TEN
Yeah, they'd love that.
But if Bush decides that that isn't going to happen, his people can handle it without the video tears.
