He can do a better job of that by refusing to give any more money to the U.N.
I am pretty sure that the funding for the UN has already been appropriated for this year, but if it wasn't, THAT would be a good thing to use against the dems that are holding up Bolton's nomination...
Bush could say that he would stop funding until Bolton is confirmed...you know how fond that Kerry and Kennedy and Biden are of the UN>
It just might get their attention!
