I would think again.... Texas and NC have seen surges in blue voters as the cities have grown from outsiders (Raliegh Durham triangle is filled with new people due to research jobs and Houston has seen increase in Northeners from oil and gas jobs (Exxon moved its HQ to suburb of Houston). I would bet anything that the addition of members is due to demographic growth in the BLUE counties of those two states. These are reflections of the increasing Blue in TX and NC so the shift is not significant as we should see same party line holds on House. The few shifts of EC will not affect an election because they have not been that close in many decades.
The states with the most representatives are California (52), Texas, (38), Florida (28) and New York (26), which account for roughly one-third of total seats in the House. CA + NY > TX + FL = no change in Presidential EC voting.
The main blue areas are Hoston, Dallas, Austin, San Antonio, laredo and El Paso... which is where the population growth was....Those red squares are mostly cattle and empty space.
And that trend continued all the way up and down the Texas-Mexico border, where Trump won 14 of the 28 counties that Clinton had nearly swept in 2016 while winning by an average of 33 percentage points.
