The difference between them is you are never getting the votes that don’t give a shit about Palestine back from Trump. His voters don’t care. Democratic voters do. When both candidates have the exact same position (and “genocide harder or lighter” isn’t a difference in position, it’s still genocide) then the issue only causes people to not vote, or look at other policies. And then you add in alienating more democrats by going further right and copying their policies. The people who like them will still vote for the republican. The people liking democratic policies will cringe and step aside.
