The biggest blue states (CA, IL, NJ, NY) are losing massively while the biggest red states (AZ, GA, NC, TX) are gaining massively.
And getting less Republican as more people move there.
Actually people typically move to places with similar ideologies. That's a false idea that migration turns red states blue. That isn't happening.
There is certainly a lot of geographical sorting by ideology, but it likely happens more at a county level than a state level. You may have conservative (and generally white) people finding their way to Collin County, TX and Cherokee County, Georgia, but you also have African-Americans moving from Chicago to DeKalb County, Georgia, and liberals moving from Boston, New York, and NJ to Raleigh-Durham and Austin.
