Mitt Romney’s campaign is up with a new ad accusing President Obama’s campaign of engaging in the type of politics he once decried.

This ad contrasts Obama attacks in the 2012 campaign with the president’s past rhetoric denouncing divide-and-conquer tactics, using three of Obama’s lines from his 2008 Democratic National Convention speech.

The quotes are:

- “If you don't have any fresh ideas, then you use stale tactics to scare voters.”

- “If you don’t have a record to run on, then you paint your opponent as someone people should run from.”

- “You make a big election about small things.”

Each time video of one of these quotes is used, the screen flashes an example of headlines critical of Obama’s campaign tactics.

The ad follows on an ad from Thursday in which Romney flatly accused Obama of lying about him and represents a renewed effort to defend himself from Obama’s attacks on his record at Bain Capital.
