When it comes down to drinking it, and the beer's good, beer isn't partisan. If you can tell if a beer's liberal or conservative just by tasting it, you're -- well, I was about to say you're better than I am, but to be honest? You're crazy.
Let's keep politics out of beer, because as I've learned in 30 years of drinking non-mainstream beer, you can't tell anything about a brewer's politics from their hopping rates. Let's leave that to the pundity types, and keep politics out of beer. Just a suggestion.
Indeed, I'd take it a step further. Pundits writing in the MSM often confuse two incredibly valuable social functions. They laud bipartisan comity like it's a Platonic ideal, and direct contempt at partisans. But we should all be partisans. We should be high-information voters with opinions strong enough to make us active participants in our democracy. But the other element is one of unity, the ability to look past our disagreements and see each other as good people despite our disagreements. Politics is great for the first, beer the second. Leave politics in the street, I say; everyone's a friend at the bar.
(Incidentally, I don't think that means we have to ignore politicians promoting beer. We just shouldn't be partisan about it. As Lew points out, Paul Ryan's a big fan of New Glarus beer, and God bless him for it.)
