Democrats were dismayed that Obama didn't more aggressively call out Romney's move to the center during the first debate. Since then, the president has been more forceful in doing so on the campaign trail and in television ads.
During debate preparations, aides are working on tailoring that message to a debate format. And they're working on balancing aggressive tactics with the debate's town-hall format, which often requires candidates to show a connection with questioners from the audience.
Romney aides suggested the former Massachusetts governor would be prepared regardless of Obama's adjustments.
"The president can change his style," Romney adviser Ed Gillespie said on "Fox News Sunday." ''He can change his tactics. He can't change his record."
The Obama campaign released a new TV ad on Monday featuring factory workers lauding the president's record on job creation.
"We have a whole second shift that we brought in, new employees, and we have a future at our plant now," says a woman in the ad titled "Main Street." It will air in Colorado, Iowa, Nevada and Virginia, all key battleground states.
