Heh.
If you want conservatives who climb, I'd venture there's a substantial number in the German speaking regions. Quite a few business tycoons are avid mountaineers there (such as Jurgen Schremp)
I'm more interested in climbing with someone who is cool, good natured, shares similar objectives and risk-acceptance, than whether they are conservative or liberal. But if it comes to a choice of politics, I prefer moderates in general, rather than shrill extremists on either side - that goes for any social interaction.
