I don´t have anything much useful to say about the ghastly Sandy Hook school massacre, and Mark may weigh in with something more considered. This post is basically an opportunity for commenters.
To give the discussion some structure, consider this paragraph in a comment by ¨John¨ at LGM:
One thing that’s worth noting is that the Democrats abandoned support for gun control around 2000 – immediately prior to a decade in which they basically lost all electoral foothold with the demographic groups whose love of guns made them give up on gun control in the first place.
What should American progressives aim for now?
Option A: business as usual; wipe away the tears, but don´t challenge the NRA or gun culture seriously. (In spite of Obama´s Appalachian winter, he handily won Michigan, Pennsylvania and Ohio, full of white hunters.) Perhaps tinker with legislation at the edges with a tougher assault weapon ban. Adam Lanza did apparently bring his mother´s legal .223 semi-automatic rifle to the school. But he reportedly left it in the car, and carried out the massacre with a a pair of her equally legal, and expensive, semi-automatic pistols.)
Option B: maximalism. Another LGM commenter, Chester Allman:
Full repeal of the 2nd Amendment and a strict Federal ban on all private gun ownership.
The full package is unatttainable; the idea is to shift the Overton window and deprive the NRA of the bloody flag, as a path to lesser, but still radical, gun control.
Option C: something in between. But what? Try to sell California´s standards in Nevada, and Maryland´s in Virginia?
