Kamala Harris’s campaign lacks detail

The month since Kamala Harris launched her presidential campaign has been a largely unprecedented spell in American politics. Never has a modern general election campaign gone from a standstill to a full sprint so  quickly.

In that time Democrats pulled together a well-scripted national convention with slickly produced promotional videos, political set-pieces and musical interludes, all done to boost the new nominee. It was a remarkable test of skill by party operatives under extreme pressure.

Over the course of four days in Chicago – and in the packed campaign rallies Ms Harris has held over the past few weeks – the outlines of her campaign strategy have begun to take shape.
