When the kitchen sink isn’t enough, do negative ads. That’s the Clinton campaign’s Pennsylvania strategy based on what Greg Sargent’s hearing:

In most of Pennsylvania’s markets, the only TV ad Hillary is running right now is a negative one — the spot hitting Obama over his “small town” comments, a political ad buyer who tracks buys in Pennsylvania tells me. The buyer says that as of this morning, that ad — and no positive spots — are running in the Pittsburgh, Erie, Johnstown/Altoona, and Wilkes-Barre/Scranton markets.

This should make all the Clinton staffers, consultants and supporters very, very proud. They can’t win the nomination, but they are willing to participate in the effort to destroy the Democratic nominee. Thirty-five years of public service and experience, yet all she can come up with is an ad twisting Obama’s remarks, which are remarkably similar to things her own husband said. Wow. It’s not only destructive, it’s sad and pathetic. And, again, it must make all those Clinton staffers so proud. So proud.

This madness has to end.
