If Biden ends support for Israel does he automatically win the election?

Current Events

Theres no winning stance a US president can have in regards to the conflict. You lose Jewish votes or lose Palestinian votes. I would hazard that most people choosing a side who are not part of those two groups or in a family with someone from one of those two groups likely have other political issues, such as the economy, bodily autonomy, and maintaining some semblance of democracy, that are more likely to determine their vote.
