Is there an app for that?

TECHNOLOGY has disrupted so many institutions that the American presidency was never likely to escape. Sure enough, a candidate has emerged from the business world, pledging to fix Washington with a smartphone. Carly Fiorina, a former CEO best known for running Hewlett-Packard (HP), a computing giant, with mixed results, has never held political office. A few weeks ago a majority of Republicans had not heard of her. But a punchy performance in a TV debate for second-tier presidential candidates on August 6th, held before a clash among top-tier contenders, propelled her up through the 17-strong field. Now Ms Fiorina is on a roll, overtaking rivals like an Uber hybrid passing a taxi rank full of snoozing drivers.
