President Obama, "Fair Share" 

What it says: "Instead of attacking folks who work for a living… Shouldn’t we stand up for them?"

What it means: Obama's not dropping the 47 percent. Or Mitt Romney's taxes. It's the incumbent's second ad this week tying Romney's comments about those who don't pay federal income taxes to the Republican candidate's own tax rate. 

Who will see it: The ad is airing in New Hampshire, Virginia, North Carolina, Florida, Ohio, Iowa, Colorado and Nevada.
