I’m in the same boat in Texas right now. Want to move to a more liberal state, and have several friends who already have.
The reason I stay is every person like me who leaves makes Texas more red. And often times, a liberal Texan is a conservative Californian/Coloradan/Canadian, so moving to one of those place will also move them to the right, so both places shift red.
Case in point. I have a friend who moved from NYC to Dallas because NY was too liberal and their conservative votes didn’t count there. They lasted 6 months before deciding to vote democrat in Texas, because red here is further right than they are comfortable with, so their move made NYC and Dallas more liberal.
