In the Pennsylvania Republican primary, a new Strategic Vision poll reports that Rudy Giuliani leads the Republican field by a wide margin. Indeed, Giuliani leads John McCain, his nearest competitor, by 25 points.  With some in the Pennsylvania legislature trying to move the primary up to February 5th, this poll bodes extremely well for Giuliani.  Indeed, if he can count on the delegates from New York, Pennsylvania, and New Jersey, it permits him to focus his attention on crucial California, Florida, and Texas.
