I don’t think it’ll seal it, but I think the whole Democratic dream of doing nothing and hoping that he says unpopular things and Biden can win without going out in public is completely dead.
We need a healthy, vibrant candidate to run aggressively against him. He can be stopped at the ballot box, but that will need an active, dynamic effort. It won’t happen on it’s own, which was clearly Biden’s campaign’s plan A.
It’s time for him to focus on being president and let Harris go out and make the case that she’s the right person to manage the four years.
