I understand why some would want him to strike back, but the President is much smarter than that. The President is focused on the big picture and doesn't have the time to address the many ankle biters who want to derail him. The facts are there for everyone to see and if they are too blind to see that these are baseless attacks on this President, it's their problem.
There is no need for President Bush to get into the mud with those losers, ignore them and move on.
