Vice President Kamala Harris said this week that she is ready to step up and be president in place of President Joe Biden.

She was asked in an interview with The Wall Street Journal if she must convince voters she is ready to serve amid concerns about Biden’s age.

In response, Harris made it clear that she is “ready to serve.”

“I am ready to serve. There’s no question about that,” she stated, adding that everyone who has observed her work “walks away fully aware of my capacity to lead.”

Harris’ comments follows Special Counsel Robert Hur’s report that concluded his criminal investigation into Biden’s handling of classified materials. Hur had said in the report that no criminal charges are warranted for Biden as a jury might see him as “a sympathetic, well-meaning, elderly man with a poor memory.”

The report pointed out that Biden has difficulties remembering details of important events in his life such as when his son Beau died and when he served as vice president during the Obama administration.

Since the report, concerns have been raised about Biden’s eligibility for president ahead of the November election. According to Jennifer Palmieri, who worked in the Obama and Clinton administrations and for Hillary Clinton’s failed 2016 campaign, the report highlighted Harris’ ability to stand in as the Democratic Party’s presidential candidate.

“There was always going to be a lot of scrutiny and pressure on her in the 2024 campaign, and that moment’s here now. I think that the special counsel’s report has sort of accelerated that moment,” she said.

Polling puts Harris as a top choice among Democrat voters if Biden pulls out of the race. A recent Harvard CAPS/Harris poll found that 15% of Democrat voters want Harris as the party’s presidential candidate.

However, the vice president’s ratings are low amid concerns that she has not put in a good performance since she was sworn into office. According to a polling from last year by ABC News, she is the lowest-rated vice president in the survey’s history. She had a -17 rating, putting her way lower below Trump admin Vice President Mike Pence who was rated -4.
