The U.S. Senate, Republican led, seems bound and determined to live down to expectations. Four bills seeking to provide better background checks for gun purchases and to keep guns out of the hands to people on the terrorist watch list utterly failed today. Our bought and paid for by the NRA Senators, almost every single Republican and a handful of Democrats, refused to do anything constructive even after the worst massacre in U.S. history in Orlando, Florida.
The American Baptist Home Mission Societies has a couple of suggestions of organizations to join to seek action by joining your voice with others. See: http://abhms.org/about-us/news/abhms-urges-american-baptists-advocate-gun-violence-prevention/ for details. The organizations are Faiths United to Prevent Gun Violence (FUPGV) and the Baptist Peace Fellowship of North America (BPFNA).
Of course, you can also vote out of office all the do nothing congresspeople and senators. I'd love to say there were politicians in office who actually listen to their constituency rather than the lobbyists. Good luck to us all.
For a list of U.S. senators who refused to vote in favor of wanted gun control regulations, see: http://boingboing.net/2016/06/20/gun-control-defeated-in-senate.html or http://everytown.org/senate-vote-orlando/ Don't forget their names this fall during the elections, when it's OUR turn to vote.
