Democrats have unified with remarkable speed behind Vice President Kamala Harris as she has taken over the top of the party’s ticket heading into the November presidential election. It may be another story when it comes to a running mate. As Pennsylvania Gov Josh Shapiro and Arizona Sen Mark Kelly have emerged as among the potential finalists, both have faced criticism from some organisations and activists who might otherwise be supportive of Democratic causes.

Harris’s team says she is interviewing six possible choices over the weekend before an announcement expected on Monday. The next day, she and her running mate will appear together at a rally in Philadelphia, then visit six more swing states. In addition to Shapiro and Kelly, Harris is said to be considering Minnesota Gov Tim Walz, Illinois Gov J B Pritzker and Gov Andy Beshear of Kentucky and Transportation Secretary Pete Buttigieg.
