In the two and a half weeks since the Republican convention,  the signs posted at vice presidential nominee Paul Ryan's campaign events have been regularly switching slogans to keep up with the Romney campaign's ever-changing focus.

In Cedar Rapids, Iowa, just as the Democratic convention was kicking off, the message was: "Are You Better Off?"

At a Sparks, Nev., event three days later, the banner behind Ryan reverted to the convention rally: "We Did Build It!"

And at events this week, the signs have been touting "The Romney Plan For a Stronger Middle Class."

Even as the signage has changed over the course of his campaign events, Ryan has largely stuck to his standard stump speech. But on Wednesday, he added a new attack line: a jab at President Obama over the 1998 audio remarks he made about government efficiency and its role in "redistribution." The audio surfaced on Tuesday.

"He's going to try and distract and divide this country to win by default," Ryan said of Obama at an event in Danville, Va. "You know, President Obama said that he believes in redistribution. Mitt Romney and I are not running to redistribute the wealth. Mitt Romney and I are running to help Americans create wealth."
