So reports USA Today. The key facts:

The Guard received 24,800 recruiting prospects from the program in 2012, documents show. In those cases, potential recruits indicated the NASCAR affiliation prompted them to seek more information about joining. Of that group, only 20 met the Guard’s qualifications for entry into the service, and not one of them joined.

In 2013, the number of prospects associated with NASCAR dropped to 7,500, according to briefing materials for the Senate subcommittee on Financial and Contracting Oversight led by McCaskill. The National Guard needs 1 million leads to meet its annual recruiting goal of 50,000 soldiers.

The National Guard spent $88 million on its NASCAR sponsorship between 2011 and 2013.
