That's according to the latest calculations of spending in the race by the Sunlight Foundation on Tuesday, the day of the GOP primary.

According to the Sunlight Foundation:

• Total candidate fundraising in the race totaled at $5,640,083

• Total candidate spending totaled at $5,579,381

• Total spending by outside groups came to $11,665,911

So candidate spending plus spending by outside group brought brought total spending in the race to $17,245,292. That figure is especially noteworthy since Mississippi does not have one media market that ranks in the top 50 in the country, according to the Sunlight Foundation.

For outside groups supporting either Sen. Thad Cochran (R-MS) or his challenger, state Sen. Chris McDaniel (R-MS), the race was a top priority. Cochran had the support of establishment Republican entities like the Chamber of Commerce while McDaniel was supported by some of the most deep-pocketed and influential tea party-aligned outside groups like the Senate Conservatives Fund and FreedomWorks.
