VP is really considered the worst job in politics but could possibly be paying off for Harris if, a big if, she can pull off beating Trump.
With so little time left, who she picks as VP will help define her, for better or worse.
In my opinion Trump made a possibly fatal mistake picking Vance. He picked him when he was feeling he had a 100 percent chance of winning. He's still favored but significantly less than a sure thing. It was an arrogant pick of over confidence. It reflects on the Project 2025 plan to create an indefinite one party maga authoritarian state (or "reich" as was in their campaign literature for a moment).
