Polls show her slightly ahead of Socialist Bernie Sanders in Iowa, but narrowly behind in New Hampshire. And the weekend brought new revelations about yet more classified and secret documents sent over her private email server when she was secretary of state.

Between now and November, she will be traversing a minefield, with detonations to be decided upon by FBI investigators who may not cherish Clinton, and might like to appear in the history books.

Clinton's charge about Donald Trump's alleged "penchant for sexism" brought a counterstrike — her being the "enabler" of Bill Clinton's long career as a sexual predator — that rendered her mute.

But with Hillary Clinton having raised the subject, it is almost certain to be reintroduced in the fall, if she is the nominee.

Then there is the newly recognized reality that Clinton, who ran a terrific comeback race against Barack Obama in 2008, is not the candidate she was. Nor is Bill the imposing surrogate he once was.

Both are eight years older, and show it. "Low energy" nails it.

Lastly, Hillary Clinton now has a record to defend as secretary of state, a four-year term in which it is hard to see, looking back, a success.
