A significant amount of money may be spent on a Senate race. Roughly $440 million could be used by candidates and their supporters. This would make the contest one of the most expensive in US Senate history, ranking second.

The race involves a Republican candidate and a Democratic state representative. Outside groups are also expected to contribute to the campaigns.

Further details about the election and its financing are available from the original report, which includes information about a high-profile fundraiser and its potential impact on the campaign.
