Is there evidence that all this money matters? One of the take aways after Nov 3 was a lot of people saying it does not that a lot of money is being set on fire. You need enough for people to know who you are. But after that?
That may be a fair question to ask in a general way.
We may have learned from the 2020 races that some seats are likely unwindable no matter how much money you throw at them.
This is not that situation.
Also, polling has them neck-and-neck. The candidates are only one point apart in the polls.
