From the States that lost seats: Republican states- Ohio and West Virginia
Democrat states – California, New York, Illinois
Swing states – Pennsylvania and Michigan
From the states that gained seats: Republican states- Texas, Montana, Florida (some consider it a swing state)
Democrat states – Colorado, Oregon
Swing states – North Carolina
So republicans lost two but gained four and democrats lost three and gained two so not much change.
What matters more then the switching of seats in the house is the electoral count per state for the presidential election and who is in control of the state legislature in each state because they control redistributing which really controls who will win more seats in the House of Representatives.
Another thing to point out is that the population growth in Texas isn�t necessarily good for Republicans. If you remember the midterm elections in 2018, Ted Cruz barely lost to Beto O�Rourke in the Texas Senate race. Texas is slowly turning blue as more New Yorkers and Californians move in. This is something we have seen when the red states of Arizona, New Mexico, Navada, Colorado, Virginia, etc.turned purple and then blue in over the last few years.
