People like to call out odd shaped districts like MD-3, MD-7, IL-4, or IL-7 as partisan gerrymandering...but it really isn't at all, it's usually done either for grouping people together (hispanics and blacks) or just silly incumbent protection districts. Neither of which really helps the "democrats" as whole in any meaningful way.
I've seen Republicans call out IL-4 more times than I can count, but no matter how you draw that district I completely guarantee you it will still be heavily Democratic.
MD-07 about the way its drawn is required, MD-03 is a monstrosity that is not needed under any circumstance, including a 8-0 Demmander.
