Since this is pretty clearly going to dominate the innertubes today:
I have no doubt whatsoever that Rand Paul and most of his supporters are appalled by what happened last night. However, I also have no doubt that in this incident and others yet to come, we are reaping the harvest of hatred sown by overheated rhetoric that treats political disagreement as betrayal and political opponents as a dire threat to America’s existence.
And on that point, it’s good to get at least SOME bipartisan agreement, notably here and here.
On the other hand, there have also been attempts to justify it and to excuse it or even celebrate it.
