Ever since she was dating Mayor Willie Brown, Kamala’s only chance at greatness, like that of a Playboy bunny hovering around Hugh Hefner’s skeleton, has been tethered to a failing old man.

And now her only real chance of becoming president rests on something happening to her boss.

Vice President Kamala Harris claimed she is “ready to serve’’ and touted her “capacity to lead” when asked last week about boss Joe Biden’s elderly age and voters’ concerns over it.

“I am ready to serve — there’s no question about that,” Harris insisted to the Wall Street Journal.

She insisted that everyone who observes her performance in office “walks away fully aware of my capacity to lead.”

What do insiders say?

Vice President Kamala Harris and her office made clear to others in the administration that her responsibilities began and ended with the factors driving people to leave Guatemala, Honduras and El Salvador — the issue Biden had assigned her to examine.

As the migration became more global, Harris’ team remained focused on the Northern Triangle and Mexico.

A former Biden administration senior official told Axios: “She’s been at best ineffective, and at worst sporadically engaged and not seeing it was her responsibility. It’s an opportunity for her, and she didn’t fill the breach.”

At best ineffective could be a good career summary of Kamala.

Kamala is ready to serve and lead, just don’t ask her to tackle the border.
