Harris, is the daughter of immigrants and a former state attorney general, prosecutor and became is currently the second Black female senator in American history.

After Biden announced he was running with Harris, he reached an 8-point advantage.

Thirty-eight percent of Americans said they would vote for Donald Trump and Mike Pence, while 46% said they would support Biden and Harris.

Biden already had an advantage over Trump, with 53% reported having a favourable view of him but has gained leverage with Harris’ 60% favourable views.

A quarter of Republicans said they had a favourable view of Harris, but only a fifth of Republicans had similar views of Biden.

Minutes after the announcement was made on Tuesday, President Trump described Harris as nasty, horrible and disrespectful.
