* Obama says he reacted to the Newtown news like a parent. But as David Remnick details, Obama must react to the shooting like a president, and jettison his conventional views about the limits of the possible.

* Though, as Dave Weigel points out, Congress also has a tangential responsibility here.

 * Still, I fear that Reid Wilson is right: The only way we’re going to have a real conversation about stricter gun laws is if Obama starts one.

* Indeed, this, from Alex Seiz Wald, on the Congressional response thus far, is rather dispiriting:

A search of the 489 members of Congress on Twitter reveals just four members who even mentioned the word “gun.” Virtually every lawmaker has put a statement on Twitter expressing their condolences, but only a tiny handful of Democratic House members have dared address the public policy question of how to prevent another tragedy like this.

* Relatedly, a good point from Reid Pillifant: Chuck Schumer has a history of pushing aggressive gun control legislation, such as the Assault Weapons Ban. Now that he’s in a Senate leadership role, will he step up this time around?

* This, from the Post editorial board, is exactly right: “it is not the Second Amendment but political cowardice that precludes sensible regulation.”

* I really hope ABC’s The Note crew is right in arguing that there’s something different about this tragedy that may actually prompt action this time. What’s heartbreaking is what makes it different: “Dead children.”

* A great David Frum rant against those who demand that in the name of “sensitivity,” we refrain from discussing the actual cause of such horrible events. Also, as Frum notes, doing more for the mentally ill and doing more to keep mass killing machines out of the hands of dangerous people are not mutually exclusive.

* Ezra Klein: 12 facts about guns and mass shootings in the United States. As Klein notes, the very act of demanding no “politicizing” of the tragedy is itself a political act designed to achieve an agenda.

* James Fallows:

Guns don’t attack children; psychopaths and sadists do. But guns uniquely allow a psychopath to wreak death and devastation on such a large scale so quickly and easily. America is the only country in which this happens again — and again and again. You can look it up.
* And this, from Alyssa Rosenberg, seems just right:
I really want someone who advocates against gun control to balance the scales for me, to go ahead and try to explain to me why the inconvenience suffered by gun owners and prospective gun owners under much tighter restrictions on the purchase of guns and ammunition outweighs the death of children in their classrooms, a place where they’re not just supposed to be safe, but to thrive.
