Is pointing out the abject failure that most of the reds states are. Probably because Democrats view all the states as Americans too and want to hanve compassion for the people suffering there.
So we've had like 20 years of Cons and their media talking about California, and for some reason Chicago and Portland, like they're these post apacaluptic hellscapes but noe one ever replying, "Um, sure, but would you like to answer for West Virginia, Mississippi, Alabama, and Louisianna?" The pocerty you see in some of those states is simply 3rd world level and a lot of the country is unaware that there are so many people in the richest country in the world living in what amount to shacks or lean-tos.
You've got Florida succeeding because rich northernoers retire or vacation there. You've got texas succeeding because of oil. And then you have a whole bunch of states that make up almost the entire worst 10 in education, income, poverty, health, crime, freedom, inequality, and basically every major metric that represents quality of life. Most of these red states can't even provides basics sercices for their residents without the blue states tax dollars coming to them through the Federal Goverment.
And this is actually the Republican plan, to turn the blue states into the worst of the red states. Places where the prisons are chuck full of young black men, places where workers have no rights and are forced to work for starvation wages, places where a hand full of the ultra rich live like kings and control everything, places where people work until they drop dead because retirement is no longer a thing. That's the Trump plan for America, to take everything from the middel class in America, everything!
