Vice President Harris's favorability numbers have increased since she became the Democratic presidential nominee, with half of Americans now viewing her favorably, according to a poll released Thursday.

Fifty percent of American adults have a favorable view of Harris, the survey from The Associated Press-NORC Center for Public Affairs Research found. Meanwhile, 44 percent have an unfavorable view.

That is flipped from late July, days after President Biden exited the race but before Harris officially became the Democratic nominee. Then, 47 percent held an unfavorable view of the vice president while 46 percent had a favorable one.

Harris quickly gathered support among Democrats to become the party's pick for president after Biden dropped out July 21.

Former President Trump remains underwater in his favorability numbers, according to Thursday's poll, which was conducted Sept. 12-16. In the previous AP-NORC poll, he was viewed unfavorably by 57 percent of adults and favorably by 41 percent. In the latest survey, 58 percent viewed him unfavorably and 38 percent favorably.

The latest poll found 38 percent of adults said they think Harris will win in November and 28 percent said they think Trump will win, while 20 percent said both have an equal chance and 14 percent said they didn't know enough to say.

A majority of respondents, 57 percent, said they think Trump would not make a good president, while views of Harris were more split: 44 percent said she'd make a good president, and 41 percent said she would not.

The poll did not explicitly ask whom the respondent supports in the race. A pair of separate surveys released Thursday showed Harris and Trump deadlocked nationally as they battle in a handful of key swing states that will determine the outcome in the Electoral College.

The latest survey of 2,028 adults was conducted online and via telephone. Of the respondents, 1,771 self-reported as registered voters.
