Obscured by the Republican bloodletting, Hillary Clinton not only is winning primaries, but beginning to look like a winner in November.

Her message and her delivery on Super Tuesday night showed how far she has come as a candidate – and how well she responded to the challenge of Bernie Sanders and the rise of Donald Trump.

Her song was better, and she sang it better. She shed the hectoring schoolteacher tone. She had the right mix of warmth, humor and resolve.

Above all, it was a positive, optimistic and inclusive message. She adopted the essence of Sanders’s message about economic inequality, but replaced his us-against-them tone with a more JFK-like “a rising tide lifts all boats.” It was “make America whole again” and “America does better when we all do better.”

Also a plus: Bill wasn’t standing behind her. Yes, Democrats love Bill and fondly remember those good old days. But Bill’s very presence looming in the background raises the trust issues that are Hillary’s biggest problem. Let him have his own stage; keep him off hers.

Speaking of Bill, history could repeat itself here with another Comeback Kid. At about this point in 1992, Bill was winning but viewed as unelectable. The Clintons and their team figured out a way to reintroduce him at the convention, and he swept to victory.

A month ago, the story was that Hillary was losing to Sanders and couldn’t win in November. To her credit, she didn’t panic after Iowa and reshuffle her team. She stuck with the plan, and she made herself a better candidate. Now, she has a clear path to the nomination, while the Republicans have a bloodbath.
