"Iowa on Steroids" Barack and Hillary prepare to fight it out in Pennsylvania.

"We operate from the assumption that Pennsylvania is Clinton country," said Mark Nevins, Clinton's state spokesman....

Meanwhile, the Clinton deviousness continues.

Clinton's advisers fended off renewed demands by the Obama campaign for Clinton to release her recent tax returns. "I, for one, do not believe that imitating Ken Starr is the way to win a Democratic primary election for president. But perhaps that theory will be tested," said Clinton communications director Howard Wolfson.

The nerve of the Clinton people—saying that asking for them to reveal relevant information to the American public is "imitating Ken Starr."

But in fact, I think it's a bad tactic for Howard Wolfson (whose political genius has always escaped me). First, it reminds us of how, when on the defensive, the Clintons always devolve into a paranoiac, us-versus-them posture, in which they are entirely right and everyone else is entirely wrong. Even more than Bill, Hillary is prone to this reflex; it's no coincidence that her inner circle is known as "Hillaryland."

Second, it reminds us of a time in Bill Clinton's presidency we'd all rather forget.

Obama—and the press—should continue to make this reasonable demand of Clinton. 'Fess up, Hillary!
