Employees of companies that do business with the city, and a few of those companies themselves, donated more than $74,000 to Albuquerque mayoral candidates through the end of March, an analysis by New Mexico In Depth found. That’s more than twice the amount the city found in an official report submitted last week, which was required within 48 hours of the latest campaign finance deadline. In 2007, Albuquerque voters approved a ban on corporate contributions and contributions from city contractors. But a 2013 lawsuit overturned those bans. As a result, the city’s purchasing department is now required to identify donors who do business with the city worth $20,000 or more during the last two years, as well as employees of those donors.
