Alpine lost population? It has only 1200 people... and that's after some reasonably robust growth in the last few decades. It also has utterly bizarre demographics - it's, like, half Mormon and quarter Peyotist. With no other established place of worship existing in the county (any practicing mainstream Christians probably drive elsewhere.)
It also votes for Democrats, against parental notification for abortions, and for legalized pot. The fact that they're losing population might mean that it'll be a while before they get a black.
