They knew that their base wouldn’t turn out for a candidate who supported a genocide. They decided to run one anyways. They thought making sure Israel could continue its genocide was more important than winning against Trump. But yeah sure blame the people who aren’t sociopaths.

I can’t give you a specific estimate but the DNC tried to burry a report that showed Kamala’s support for Israel cost her key votes. That should tell you what you need to know.
That said you can also just look at the vote differences between 2020 and 2024. Kamala lost more votes than Trump gained relative to the 2020 vote counts. It’s clear from those results that democratic turnout was depressed in 2024 when the admin’s policy towards Gaza was one of the most obvious divides between democratic leadership and democratic voters.
