Can $1 billion buy victory in the midterm elections? Some Republicans fear the answer is no

Money is being spent heavily on campaigns. A large amount, over $1 billion, is available to one party. This funding is distributed among several groups.

A key group has a significant amount of cash, nearly $416 million, which it began using more heavily in recent months. However, this spending may not have started soon enough to be effective.

Further information about the campaign and its financing is available from the source, including details about advertising time and costs.
