House Speaker Nancy Pelosi (D-Calif.) downplayed the decision that Democratic presidential candidate Joe Biden will make on who will be his vice president.

“I don’t think it matters who the vice presidential candidate is historically. It has never mattered,” Pelosi said, adding, “Lyndon Johnson for victory, Sarah Palin for defeat, but by and large, it’s really all about the two candidates for president, and I’m so proud of Joe Biden,” she said in an interview with MSNBC on Aug. 7.

“I always defer to the judgment of the candidate in selecting the vice president, in terms of who he has confidence in, that he can work with, who could serve in case of emergency, and also that would do no harm in the presidential, but it’s not, I think, making a difference,” Pelosi said in her speech.

The name of the person who will run for vice president in the next election has quite a stir, less than three months before the vote.

Biden’s campaign had initially suggested that she be an African American woman of preference, which raised the parameters based on sex and race, and now Pelosi is downplaying the election for which at least a dozen candidates are running.

Among them are Sen. Kamala Harris (D-Calif.), Obama’s former National Security Adviser Susan Rice, and Rep. Karen Bass (D-Calif.).

Although Pelosi considers the profile of whoever accompanies Biden as presidential candidate not very relevant, for some of the analysts the importance of this position is made vital by Biden’s age and the frequent accusations of mental decline that have been made against him.

While Biden claims he has not done any tests to determine his mental health status, and seems unwilling to do so according to a recent interview, this is a concern for many voters.

This year’s election is unusual in that it would be the fourth time a woman would run for vice president, and eventually the first African American to hold that position, alongside Biden.

In U.S. history, at least nine vice presidents have come to the presidency by succession, which is 20 percent, a remarkable percentage, according to History.

In eight of the cases, the vice presidents replaced the incumbent upon his death, and if Biden reaches his 78th birthday upon taking office should he win, the likelihood of such an event increases.

A survey conducted by Zogby Analytics revealed that most voters surveyed believe Joe Biden is potentially in the early stages of dementia.

“Most voters believe Biden is in the early stages of dementia; 60 percent of younger voters believe it; undecided voters are less likely to think Biden has dementia,” Zogby said on June 17.
