RE: who knows what might happen with one or more new Justices if the Republicans win in 2016.
1) Who knows which Justice will be gone after that?
2) What if Hillary (with nearly a billion in her war chest and with a score of Republicans vying to be the candidate), wins?
Yep a lot can happen. Most of what has been happening recently has been pretty bad so being optimistic probably is unrealistic. The US has entered into an era of decadence and hedonism. It will not recover with one election.
