I know it is upsetting to a lot of folks, but there really isn't a lot of good that Bush can do at this point. He can veto bad legislation and that is about it. He can't lower taxes, reduce the size of government, get conservatives on the bench, secure the border, etc.
He didn't do all of those when he had a Republican Congress, either.
In fact, the only one of those he did on his own was lower taxes. That and conservatives on the bench, but he had to have his feet held to the fire on that score....
the Speaker of the House has nothing to do with the judicial confirmation process...
