I could write my own thoughts but why bother when someone has done such a superior job covering all the angles. I highly recommend checking out Joe Gandelman's blog post this morning at The Moderate Voice.

Senator Hillary Clinton got the Pennsylvania Democratic primary victory she needed so she could press the case that she should continue in the race because rival candidate Senator Barack Obama could not close the deal after vastly outspending her.

But her victory margin (a 10 percent margin, at this writing) most certainly means that the increasingly ugly battle for the Democratic party nomination will go well into June…and perhaps all the way to the convention.
