WELL-OILED MACHINE: Revelation About Hillary Clinton Emails Catches Democrats Off Guard.

The revelation that Hillary Rodham Clinton conducted government business entirely on a private email account as secretary of state has blindsided the Democratic establishment.

It was a bracing reminder of the risks entailed in the party’s all-but-all-in bet on Mrs. Clinton so early in the presidential nominating process. And it left Democrats contemplating the prospect of yet another long cycle of dramatic Clinton flare-ups — the type that President Obama obliquely campaigned against in 2008.

The report on Mrs. Clinton’s emails, published by The New York Times late Monday night, left many Democrats privately expressing wonder as late as Wednesday morning that Mrs. Clinton and her aides had not anticipated the political problems that this could create.

Huh. A lot of Dems have told me that Hillary is “as oiled as a Diesel train,” so I expected things to be slicker.
