“Trump knows this. He openly admits that this plan does the exact opposite of what he promised voters during the campaign. And he supports the plan anyway.”
Because he knows his brainwashed supporters aren’t going to care. He already knows they don’t care if he lies or goes back on his word — that’s already been proven. He knows they will continue to support him, no matter how badly he treats them, and he knows they will continue to vote against their best interests. And he’s probably right.
