Voters in Colorado, Missouri, Michigan and (it looks like) Utah have voted to establish independent commissions to draw state district lines. Ohio voters did this in the spring, and Pennsylvania had it forced on it by a court. If you want to see what a non-gerrymandered state looks like, see Iowa.
Once you add the states without the potential for gerrymandering since they only have one representative (MT, SD, ND, DE, AK, VT, WY), we're more than quarter of the way toward rational, fair districts.
