IMO, even if gerrymandering doesn't have a huge effect on seating in Congress (perhaps it has more effect on state level politics? I didn't read the other commenter's link so I won't make any claims) it makes a lot of districts non-competitive. The effects of this are hard to quantify and so we don't hear as much about it, but I argue that they are at least as profound as the numerical differences in congress on our national dialogue.
