Go to a Democratic house party, small fundraiser, anything like that, and you're unlikely to find any Coors products. That's not just because the chairman of the board, Pete Coors, made an unsuccessful bid for U.S. Senate as a Republican in 2004. It's not because the company's PAC gave about 70% of its donations to Republicans (a ratio that remains approximately the industry standard).

The Democratic party isn't a fan of Coors because of its history of supporting conservative causes. Millions of dollars from the Coors company have landed in GOP hands. The Coors family helped found the conservative Heritage Foundation. Some liberals even tried to boycott Coors when the company gave money to anti-affirmative action activist Ward Connerly for Proposition 209 in California several years ago.

So it seemed a little odd to find, in an article detailing corporate contributions to conventions, that Molson Coors Brewing is giving $1 million to Democrats when they throw their quadrennial convo in Denver next year. How will rank-and-file delegates to the convention react when they head out for a beer and find nothing but Coors? Prepare for some strong words.

Miller, the only major brewery left which marks their bottles as "Union Made," could swoop in to save the Democrats some face, though playing on another beer company's home turf might be too much like a corporate gang war. Besides, Milwaukee is much closer to Minneapolis, where Republicans are holding their get-together next year. Ah, refreshing irony.
