It damn sure isn’t President Obama, who is unafraid to show his grief, anger and determination to combat gun violence.

No. It’s the cowardly Republican politicians who are so scared of the NRA they react hysterically over the smallest steps to keep guns out of the hands of criminals and the mentally ill.

The NRA has held sway for so long that politicos accept its invincibility as a given, as set and eternal as the sunrise.

But sometimes the tides of human affairs – and politics – shift suddenly. The old order is swept away, and a new reality takes hold.

We could be at that tipping point now. If that turns out to be the case, it will have started with the President’s heartfelt tears and steely anger.

Go, Obama.
