Clinton designated half of Utah as a national monument with the stroke of the pen (...law of the land,... kinda cool). Why can't President Bush simply designate this national monument as a national monument?

But if a new Democrat president is ever elected, he could undo the order.
By passing a bill in congress, only congress can reverse it's decision.
And that would be a much tougher road.
