Joseph,
I don’t know Boro Park and Williamsburg, true. But I know plenty of Monsey and it applies there. I am not saying that Torah requires one to follow the Democratic positions on Climate change or immigration, but only that the Democratic positions are more in line–in a general sense–with Torah Hashkafa.
With respect to Climate Change, there is no Torah basis for being skeptical and usually we follow chachmei umos ha’olam when it comes to scientific metzios. With respect to immigration, I am referring to the attitude toward immigrants generally, not the question of whether it should be done illegally. I think most Democrats agree (Obama certainly did) that immigration must be done legally. The issue is what do with those who are already here and how vicious should the US be in preventing more people from coming in illegally.
