I'm not a big believer that more and more money wins Presidential elections. I think every Democratic and Republican nominee in recent history has had plenty of money to get their message out.
It's never as simple as "more money wins".
But you do need to
have the money coming in, and Trump was not doing so great there.
But it is also
who donates and what kind of access they think they can get.
Vance is Silicon Valley money - Musk and Thiel.
Trump seems to want that more than old business money because he gets along with them better.
I don't know who the Democratic nominee will be and how this will go down with donors. Let's just say that in a normal Presidential election both candidates are oversubscribed.
The big money donors on the Dem side are going to have to decide if they are ok with Harris or not.
The ones who had big dreams of putting in their own choice seem to have not anticipated the push back supporting her.
They know they can take down someone late in the game now, though, and might try to push anyway.
Or they might decide this will do and save ammo for later.
I really don't know.
