Wien, Österreich
I live in Austria, in Vienna specifically. I live in what is probably the "reddest" city in the western world, which has had a mayor from the Social Democratic Party of Austria (SPÖ) for more than 70 years now unbroken and where more than half of all families live in socially owned or socially subsidized housing (like the massive Karl Marx-Hof complex which houses more than 10,000 people and is the largest social housing project in the west). It's also routinely named the #1 quality of life city in the world, is extraordinarily safe and despite a hugely diverse population sees very little civic strife between various religious and ethnic groups.
Austria, and Vienna in particular, is very, very red. And it's worked extremely well here for the same reason many systems can work (and opposite the reason that governments and countries completely fail) - people are vocal and active in politics, vote out underperforming, corrupt or scandalous elected officials and hold them to a high standard. There's a strong respect for the rule of law and very low corruption. Effective governance has a lot more to do with being effective than about the belief structure behind it. People treat politics way too damn much like religion and not nearly enough like the boring day to day responsibility that it really is.
