Gorsuch's ideology is not in line with a divided country. He is far to conservative. Hardiman would have been a much better choice. The problem for the GOP with Gorsuch and the removal of the filibusterer is that the dems are now likely to nominate very liberal people to counteract people like Gorsuch. There is going to be very little common sense in SCOTUS because it will just be ultra conservatives and ultra liberals writing opposite opinions.
The pendulum will swing back, especially if you consider that the GOP isn't doing very well with minorities and that is the biggest growing group.
