The valid alternative to Trump is not Biden. It's RFK.
Biden is a brazen neocon. He has sent billions to Ukraine and Israel, driving up inflation and debt, making the middle class poorer.
Trump is likely beholden to the same neocon forces.
RFK (though not great on Israel) is the only one who's aware of this problem. He's the only candidate screaming "stop the wars, rebuild the middle class."
