As Joe Biden begins scrutinizing and vetting potential running mates, a former 2020 Democratic presidential rival, Minnesota Sen. Amy Klobuchar, is emerging as seemingly safe and reliable.

Doing so would go against the wishes of many party activists who are demanding that Biden, vice president under President Barack Obama and now the presumptive Democratic nominee, choose a black woman or vocal liberal. Biden has pledged to choose a woman as his running mate, and Klobuchar would help him keep moderate voters in his fold — a crucial voting bloc in a tight race against President Trump.
