OPINION - Ostrich Joe Biden should hand over to Kamala Harris

With lashings of orange bronzer, a frozen face and gleaming white teeth, Joe Biden is doing his best ostrich impression by insisting he can win the US election and serve as president until he is 86. Senior Democrats are quietly knifing him in off-the-record briefings, but are queuing up to profess their loyalty in public. It is a wretched affair, reminiscent of the way cowardly Republicans kow-towed for years to Donald Trump while privately claiming to despise him.
