No.
You cannot hold us hostage and blame us if Trump wins. Biden can stop supporting a genocide. The DNC could drop him as a candidate.
This is a choice the Democratic elite are making. And if there are no consequences here then there's no hope to get off this pro corporate train into fascism either. They'll just keep following the GOP to the right until in 2028 it's, "we have to support Harris Youth because DeSantis would dissolve Congress."
I've watched the Democrats dive to the right every single election in my life, except one. And I've held my nose every single time they did it.
