"Two private polls conducted in a swing New York House district and reviewed by POLITICO — one in September and another in March — found former President Donald Trump leading Biden there by 1 point, a virtual tie. And public polls over the last four months found Biden’s lead had winnowed to just 8 points across New York — an unusually narrow gap in a state where Democrats outnumber Republicans 2 to 1.
“We’re still acting like this is a one-party state, which for pretty much 20, 25 years it has been,” Democratic Manhattan Borough President Mark Levine said. “I truly believe we’re a battleground state now.”
A Biden lead of 8 points in a state he carried by 23 in 2020 is a huge loss of support.

Polling shows that people don’t hate Harris more though. In this context she’s more popular than both Biden and Trump.

"The national survey found 52% of registered voters disapprove of her job performance as President Joe Biden’s vice president.
About 36% approve of how she’s handling the role, trailing Biden’s almost equally dismal 41% approval rating.
Roughly 38% of Americans have a favorable view of Harris, lagging behind Biden, who is viewed favorably by 41% of registered voters. Former President Donald Trump, the presumptive Republican nominee, was viewed favorably by 40% of respondents in the poll."
You have to look at aggregate polls, single polls don’t provide a clear picture.
Biden’s approval rating is -19.3 https://projects.fivethirtyeight.com/biden-approval-rating/
Trump’s favorability rating is -11.8 https://projects.fivethirtyeight.com/polls/favorability/donald-trump/
Harris’ approval rating is -12 https://projects.fivethirtyeight.com/polls/approval/kamala-harris/
Perhaps look at more recent polling after Biden’sfailure in the debate, not numbers from May.

She’s more popular with women and independents than Biden, which are two of the main groups Biden has been attempting to court to make up for losing the anti-genocide vote. There are no downsides, Biden’s a guarunteed loss, his numbers match up with every losing presidential candidate going back decades.
Harris, while hindered by being in the administration, can also distance herself from Biden’s overwhelming support. She doesn’t need to say “from the river to the sea”, just being wishy washy could give some people the room to vote Democratic for other reasons.
