Not really. It's not surprising that Republican have such a lopsided majority in some states.
The cold hard truth is that Democrats are highly concentrated in urban districts that vote 70-95% Democrat, and Republicans are concentrated in rural/suburban districts that vote 55-75% Republican. That's just the way it is
which is why I find it interesting that in 1976, it was the opposite. There were 24 districts in Texas back then. Carter won the state with 51% of the vote yet won 18 of the 24 districts. The republican vote was concentrated in the 3rd district (72% Ford) and the 7th (73% Ford). The four other districts Ford won were won by small margins and because they were ancestrally democratic and had senior incumbents the democrats had a 22-2 delegation.
