in that he always comes back alive just when you think he's politically dead.

I thought he was finished when the Access Hollywood tapes came out - no way he could come back from it and yet he did. Then Mueller and Ukraine should've done it but it didn't.

Joe is in a good position but realize that most people don't care much about Trump's taxes, but about his horrible record as it relates to their everyday lives, ie his mismanagement of covid which has resulted in 200k dead Americans, his tax cuts for the rich, his assault on healthcare and preexisting conditons and social security/medicare, his disregard for democratic norms, his war on voting, his racial diviseness and chaos, etc. The tax story helps to strengthen Joe's message but by itself can't knock Trump out.
