Let's look at the actual facts.
From 2020 - 2025 only seven states have seen a decrease in population. Hawaii and West Virginia have seen a drop of about 1.5%. New York and Louisiana have seen drops of just under 1%. Illinois had a drop of .8%. California saw a drop of .5% and Mississippi saw a drop of .24%. Three of the seven states are not Democratic states.
So the facts show your original claim of Dem states being depopulated to be false.
