Yet another poll out today of the Pennsylvania Senate primary. And this one — from Suffolk — shows Sestak up by 9.

This one really may come down to whether the Democratic machine in the state can pull Arlen over the finish line.
Late Update: This is one reason why poll trend graphs are so fun (at least for political geeks). What you see in the graph is that the composite of all the polls shows that Specter’s support has been strikingly static. It’s almost an unbroken straight line going back to the Fall. No one’s come or gone. But starting in late February basically all the undecideds began to break in Sestak’s direction.
