"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.

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.
