Analytics website Crowdpac looked at the political contributions of employees from four major coffee chains– Starbucks, Dunkin’ Donuts, McDonald’s and Krispy Kreme–and found employees of the former two companies donated more often to liberal politicians while employees of the latter two tended to contribute to conservatives.

“We analyzed our historical database, containing every political contribution since 1980, and found that just as you can get your coffee dark, with cream or with room, you can also get it in various shades of red and blue,” a Crowdpac spokesperson told Breitbart News.

Starbucks has come under fire for removing all symbols of the holidays from its coffee cups for the upcoming holiday season, opting instead for plain, solid red-colored cups. The backlash even prompted Republican presidential candidate Donald Trump to suggest a boycott of the world’s most famous coffee chain.
