I don't see how you could make that assumption. Look at their policies - "bail reform", "police reform", and embracing "peaceful protests". These are PARTY POLICY now. Then, look at the results - triple-digit-percentage crime rate increases, cities in ruin, in flames, in rubble. Residents fleeing and moving. Cops quitting or retiring. Criminals on the streets, with no fear about incarceration because they know a) cops are afraid to touch them in the first place, and b) "bail reform" means that even if they DO get arrested, they'll be back out before dinner.
Beyond all that - look at their underlying policies that have been in place for decades. Poor schooling. Welfare state. High unemployment. Compare a downtown Chicago, or Baltimore, or L.A....to a downtown Tyler TX, or Lafayette LA, or Scottsdale AZ. Look at the people living there. Look at the quality of life.
Compare, and contrast. Hell, be objective - pick a city. Look at the quality of the city. Compare it to other cities. Photos. Per capita income levels. Cost of living. How clean is it? How pretty is it? What are the schools like? What's the population consistency like - do people come there and stay? Or are people leaving on a regular basis? THEN, once you do all that, look at who runs them and how they correlate.
These places aren't the way they are, because of geography.
It's no narrative - it's fact. Numbers on paper, don't lie.
