Nothing is stopping any of them from moving to a 'murder all the babies you want' leftist controlled state. Pay massively more in taxes, be in huge and constant danger from the coddled criminal elements and radical leftists when they decide to riot, loot, burn, mug, and murder inside a Dem Party controlled city, and have it essentially be illegal to defend yourself.
I am certain that huge numbers of Texas upwardly mobile women will just flock to Chicago, Seattle, New York city or L.A.
