There is a fine line between championing diversity and embracing identity politics. In practice, it should be a bright red one. But, as Joe Biden, the US president-elect, is discovering, it is hard to please all your constituents all of the time.
In the past three weeks, Mr Biden has made good on his promise to unveil “the most diverse cabinet in history” — with several big appointments to come. Yet the pressure on him to be even more inclusive has only grown louder.
The danger is that Mr Biden will be lured into an unwinnable game of tokenism. He is almost destined to fall out at some point with the progressive wing of the Democratic party. With the Senate likely to be controlled by the Republicans, Mr Biden’s only chance of passing significant bills will be to strike deals with the few moderate Republicans and hope that more leftwing senators, such as Bernie Sanders and Elizabeth Warren, will see no option but to vote Yes.
