5 major questions facing Kamala Harris now

Few candidates have had as successful a campaign launch as Vice President Kamala Harris, raising hundreds of millions, moving up in polls and energizing the base. The Harris campaign notched an additional $36 million in the 24 hours after announcing Minnesota Gov. Tim Walz as her running mate, and as the Democratic ticket swung across the country, it drew large, raucous crowds.

She’s growing into her new role as she faces economic uncertainty, a politically volatile situation in the Middle East and questions about her own ability to meet the challenges of a tough campaign.

From major policy issues to the campaign’s media strategy, here are five big questions facing the ticket in the months ahead.
