You really have an amazingly simple view of life. Everything is black and white to you.
Gerrymandering is a fact and not an excuse. No one is using it and then not trying.
You can understand where things are rigged against you and develop a strategic plan to try to win. That pretty much describes Iowa football. Ultimately, from a strategic standpoint, this is where Hillary failed. However, she lost by a mere 77k votes. That would be like Iowa losing in OT to Ohio State and you saying, "Time to rethink every single thing Kirk Ferentz does"
So simple.
The democrats have lost how many congressional seats, Governor races and now the White House since 2010? If KF was getting his teeth knocked in at that rate I would suggest wholesale changes.
