Stoled from the Slacktivist, who is quoting Ezra Klein:
Gun control has emerged as an unusually clarifying test case for how Congress really works. On one side of the ledger is most everything that we think moves Congress: Public opinion, a national tragedy, the president’s bully pulpit, elite opinion. On the other side is everything we wish didn’t move Congress: a powerful but increasingly controversial interest group and, arguably, the minority’s natural incentive to foil the majority’s agenda.
Guess which side is winning?
