Also I just looked at Maryland. I can't figure out just how many people voted for the GOP in the House but 35% voted for Trump - a reasonable proxy I think. The GOP for that gets 12.5% of the House representatives.
My larger point is that the GOP isn't without representation. Heck if the GOP had zero out of 8 seats and was getting 55% of the vote they wouldn't be without representation. They'd just be getting representation that wasn't proportionate. Even in that case I think they'd be getting more then you suspect - that degree of gerrymandering generally means that no one has a huge margin and even the most ideological politician will cast a glance backwards every now and then on a tough vote.
The chart was based on 2022, the first election after redistricting. Since it wasn't a presidential election, and Trump wasn't present as a polarizing influence, it makes sense that the numbers would change greatly in 2024. You can do the math on your own for Maryland:
In both cases the Republicans win one house district in a very boring district boundary. The republican advantage comes from local senate and house election results.
