Maybe I'm wrong but
This event has done two things: it's caused Dems to grow a pair, and it is exposing the GOP influence of the gun lobby.
While Joe Scarborough may be now a RINO, he was rated A+ by the NRA for his stance on guns when he was in Congress. A staunch libertarian all the way and an avowed conservative Republican.
Earlier this week he gave a mea-culpa on-air where he said he was wrong, that the safety of our children are the most important thing, and that this event changed him, and changed America. Call me naive, but I belive that.
