Three polls out this morning in Pennsylvania’s primary: the Morning Call tracking poll finds Sestak and Specter tied at 45 percent each; Quinnipiac finds Specter ahead by 2 percentage points, and Franklin and Marshall finds Sestak ahead by 2 percentage points.

I’m sticking with my prediction of a Sestak win, but the optimum scenario for Republican Pat Toomey — a narrow Specter win that leaves a lot of Democrats unenthused about their turncoat nominee — still looks like a real possibility.
