This is big but the way it has come forth takes too much time and/or a long read or viewing. Where are the brains who can cut this story down to explain it in a 30 second ad? This really shows the real Obama more than almost anything else. It covers the entire spectrum of negativity, deceit and dishonest character.
An ad merely has to show Obama railing about the Stafford Act and New Orleans--freeze frame--with a voiceover pointing out that Obama was one of only 14 senators to vote AGAINST the Stafford Act. Then repeat the clip for emphasis.
If this doesn't show what a loathsome individual Barry is, I don't know what will.
