Josh Shapiro, the Democratic governor of Pennsylvania, is widely speculated to be among Kamala Harris’s vice-presidential finalists.

Martin Pengelly explores Shapiro’s background for the Guardian:

July was the best grassroots fundraising month in presidential history.

Team Harris raised more across grassroots channels in the four days following President Biden’s endorsement of Vice-President Harris than Trump’s big donor-reliant operation raised in the entire month.

More than 3 million donors made over 4.2m contributions – with more than 2 million donors making their first donation this cycle.

This month, 94% of all our donations were under $200, and teachers and nurses continue to be among the most common donor occupations.

Compared with June, we saw more than 10 times the number of gen Z donors, and more than eight times the number of millennial donors.

Sixty per cent of all donors in July were women.

Coalition groups that organized calls since launch – like Black Women for Harris, Latinas for Harris, and White Dudes for Harris – raised more than $20m for Team Harris.
