This person you're discussing would've voted in New Jersey, which was overwhelmingly won by Harris. You're totally discounting a valid frustration with Liberals who follow a politics of aesthetics instead of policy. Things probably will be much worse for the Palestinians with Trump, but there has been zero evidence the situation would've gotten any better under Harris. There's been an ongoing genocide with no stop in sight for over a year and the US is actively funding it right now.
This guy rooted for the National Guard at Kent State.
