Location plays a huge roll. Our culture pays attention to hipsters because large cities are were our big media outlets are located. But, most of us are suburban or exurban. Hipsters not so common there. I have experienced Christain cycling clubs way out in the suburbs. Doubt they are liberal. Physical fittness can appeal to all regardless of one's politics. / Another possibility with resource shortages and draught , maybe even Republican values might change/ Yes, urban residents with their over crowded highways are likely to have an urban agenda. But, the better bike infrastructure i think is out in the suburbs where there is more space. And likely more Republican. / About Hipster. I hate that adjective. Does one have to be a hipster to be liberal. Hope not. Cause I doubt I could be one.
