She is running, and she will run no matter what. If the polls say she will lose, she will make the polls say otherwise or else.
This is a scorpion-on-the-frog situation. Will to power is Her essential nature. She cannot sit aside and retire in peace, it is not who she is.
Making public polls say want she wants is not at all what matters. It’s the internal polling that the parties use that matters and if they show her losing to Trump, she will not run.
