Former President Barack Obama and former State Secretary Hilary Clinton on Tuesday, Aug. 11, expressed support for presumptive 2020 Democratic presidential nominee Joe Biden’s selection of Sen. Kamala Harris (D-Calif.) as his running mate.

Biden announced he chose Harris to be his running mate earlier Tuesday on Twitter.

“Joe Biden is running to restore the soul of the nation and unite the country to move us forward. Joe knows more about the importance of the Vice Presidency than just about anyone, and he is confident that Kamala Harris will be the best partner for him to finally get the country back on track,” the Biden campaign said in an email.

“Since Donald Trump became president, he has made everything worse. He has pursued economic policies that reward wealth over work and benefited corporations and his buddies over working families. He has walked away from American leadership on the national stage. He has used division and stoked hatred for political purposes to pit Americans against one another,” the campaign email stated.

Obama addressed Biden’s move, saying that the former vice president “nailed this decision.” “By choosing Senator Kamala Harris as America’s next vice president, he’s underscored his own judgment and character,” Obama tweeted. “And now Joe has an ideal partner to help him tackle the very real challenges America faces right now and in the years ahead,” he added.

Hillary Clinton was the Democratic presidential nominee in 2016. She also supported Biden’s decision, calling voters to cast their ballots in November to get the former vice president and Harris elected. “I’m thrilled to welcome @KamalaHarris to a historic Democratic ticket. She’s already proven herself to be an incredible public servant and leader. And I know she’ll be a strong partner to @JoeBiden. Please join me in having her back and getting her elected,” Clinton tweeted.

A new poll released on Monday showed that 43 percent of likely voters nationwide had a favorable view of Harris, with 36 percent saying they had an unfavorable view.

The poll indicated that Harris had a 64 percent–15 percent favorable rating among Black voters, 41 percent–39 percent among White voters, and 39 percent–32 percent among Latino voters, reported Fox News.

“I think she energizes a base that’s already pretty energized,” said Mo Elleithee, a senior spokesman for Hillary Clinton’s 2008 presidential campaign. Later, Elleithee served as communications director for the Democratic National Committee.

“Her numbers are incredibly high with African American voters, with people who don’t like President Trump, with a lot of the key constituencies of the Democratic base,” he added.
