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: https://en.wikipedia.org/wiki/2022_United_States_House_of_Representatives_elections_in_Maryland https://en.wikipedia.org/wiki/2022_United_States_House_of_Re... and https://en.wikipedia.org/wiki/2024_United_States_House_of_Representatives_elections_in_Maryland https://en.wikipedia.org/wiki/2024_United_States_House_of_Re... 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.
