@augieray I do not think my reply was significantly more glib than your original post.
There is a lot that can be done to win back voters who are turned off of Biden because of the war. For example, emphasizing the leadership role the US has played in the ceasefire process. Getting food and medicine into Gaza. Conditioning aid.
Blaming people who oppose ethnic cleansing for the return of Trump isn't it, though.
I wish you good luck with your effort!
