The massacre of 20 children at Sandy Hook Elementary failed to generate the political will for some form of gun regulation in 2012. Now 49 people have been gunned down at a gay club in Orlando – in the worst mass shooting in American history, and Democrats are feuding with Republicans again in the House and the Senate. The latest proposals involve the "gun-show loophole" and the no-fly list. Are the prospects for action better now than they were four years ago? The country already has more guns than people, and the NRA is especially powerful in an election year.
