Obama urges voters to take 'revenge' on Election Day, Romney team rips 'terrible' message

ETNA, Ohio -- The Romney campaign ripped President Obama after the president suggested Friday that supporters take "revenge" by voting against the Republican nominee.

During a speech in Springfield, Ohio, Obama talked about the Clinton administration and its economic plan that "asked the wealthiest Americans to pay a little bit more." Then he mentioned Mitt Romney, drawing boos from the crowd.

"No, no, no -- don't boo, vote," Obama said. "Vote. Voting is the best revenge."

It was a slight riff on the president's usual interjection when members of the audience start booing.

But the Romney camp claimed Obama's remarks draw a clear distinction between the two men, just four days before Election Day.

"I think it's a terrible message to be sending," Romney senior adviser Kevin Madden said. "The contrast could not be more stark. Governor Romney is out campaigning on a positive message of change while the president is talking about revenge."

The Obama campaign lashed back.

"We'll take a lecture from the Romney campaign on positive campaigning when they stop scaring auto workers, pull their cynical Jeep ad off the air and apologize for falsely claiming that Chrysler is moving Jeep production to China," Obama campaign spokeswoman Lis Smith said, referring to a Romney ad targeting Obama's record on the auto industry. "That's their closing argument and there's nothing positive about scare tactics and dishonesty."

Romney started the day with an event in Wisconsin before moving on to the all-important battleground of Ohio.

Obama spent his entire day in the Buckeye State, speaking at three rallies.
