Charles Franklin scans the charts. The news isn't good for Manhattan's Mussolini:
Since early March, Giuliani's support has fallen by an estimated 8 percentage points. McCain's fell by 10 points since January. And the rate of decline has been a bit steeper for Giuliani than for McCain. The saving grace for Giuliani has been that he started his decline from a higher point, around 33%, while McCain's slump started down from 25%.
Giuliani's national slide is also mirrored in the early primary states, as is the case with McCain.
