SALT LAKE CITY — Former Vice President Joe Biden is rumored to have narrowed the search down to three candidates for who will fill his old shoes if the presumptive Democratic nominee wins this fall’s presidential election.

Per a promise Biden made in March, the Democrat’s ticket would include a woman as vice president.

“If I’m elected president, my cabinet, my administration will look like the country, and I commit that I will, in fact, appoint a, pick a woman to be vice president,” the former vice president said during a debate in March.

The vice presidential selection has come under additional scrutiny, as 77-year-old Biden — three year’s senior to President Donald Trump — would be the oldest person ever elected president.

Here are the front-runners, according to the latest news reports:

Sen. Kamala Harris

Harris is the former attorney general of California and was the second African American woman ever elected to the U.S. Senate, taking office in January 2017.

The 55-year-old senator representing California is arguably Biden’s top choice, according to Politico. If Biden wants the Democratic ticket to “look like the country,” selecting a woman of color like Harris would uphold that desire.

Harris, who ended her own presidential primary campaign in early December 2019, endorsed Biden this past March.

The senator has said she would be “honored” to be on the ticket, but has not publicly campaigned for the position. Her own internal polling during her short presidential campaign, showed Harris doing well in Democratic strongholds, among Black and liberal women and young people, according to The New York Times.

While aggressively standing up to Biden during primary debates, Harris has dedicated much of her recent Twitter posts to supporting Biden’s presidential campaign.

Former Ambassador Susan Rice

Rice is a highly-qualified career diplomat and national security expert that served in adviser roles in both the Clinton and Obama administrations.

Rice, 55, was ambassador to the United Nations (formally called the U.S. Permanent Representative) from January 2009 to July 2013 and then was President Barack Obama’s national security adviser.

“I think I could bring my experience of almost now 20 years in the senior levels of the executive branch to bear to help tackle the most pressing problems we face,” Rice said on NPR’s Morning Edition last week.

Rice endorsed the former vice president in early March.

She has been criticized for her involvement in the Obama administration’s explanation of the Sep. 11, 2012, Benghazi attack. If chosen as Biden’s running mate, she will expose Biden to Republican attacks on those events, where four Americans died, including an ambassador.

Sen. Elizabeth Warren

Warren, of Massachusetts, is another rumored top choice who campaigned against Biden in the presidential primary.

We both want the same thing. We want this country to work, and we want it to work for everyone,” Warren said on MSNBC in April.

Warren, 71, who also ran in the 2020 Democratic primary, waited to publicly endorse Biden until after progressive independent Sen. Bernie Sanders of Vermont had bowed out of the race in early April.

She has already received vice presidential endorsements from progressive organizations Progressive Democrats of America and RootsAction, a key Demographic for Democratic voters who would have preferred to vote for Sanders in November.

“She has the tenacity and expertise to help ordinary Americans steer through this crisis, and she’d be ready to govern on day one,” the organizations wrote in an open letter to Biden.

Warren has also helped the Biden earn a total of $7.7 million for the campaign, more than any other potential vice presidential candidate, Politico reported.

But, if Biden is looking to appeal to voters of color, selecting Warren may not help the ticket as much as Harris or Rice.

Others given serious consideration are Sen. Tammy Duckworth, D-Ill., Michigan Gov. Gretchen Whitmer and Rep. Karen Bass of California.

There are less than 90 days until the November election and two months before the sole vice presidential debate, which will be held at the University of Utah on Oct. 7.
