I see even Fox News has Matthew McConaughey blasted on their main page today regarding his speech at the White House, and seems to be casting him in a positive light for "sensible" reform. Which includes red flags, enhanced background checks, 21 or over, and waiting periods, which surprisingly, I hadn't heard talked about much by politicians. That's usually a favorite, though it would have done nothing in these last two incidents.
It seems to me that something distasteful will pass, given that so many establishment and squishy Rs, and non-gunny conservatives in general, want to "do something".
