President Barack Obama rejected on Monday the assertion of his opponent Mitt Romney that the tone of his re-election campaign has been overly harsh.
At an impromptu news conference, the president told reporters his speeches have been centered on substantive issues like taxes and spending.
"If you look at the overall trajectory of our campaign, and the ads that I approved and are produced by my campaign, you'll see that we point out sharp differences between the candidates but we don't go out of bounds," said Obama.
Romney and his running mate Paul Ryan stumped in Manchester, N.H. and told voters they will not touch seniors' health care.
"I think the future to saving Medicare is let 50 million seniors decide how they get their health care instead of relegating that decision to 15 unelected bureaucrats," said Ryan.
The Republican candidates also told the crowd they will not raise taxes on anyone.
Obama will be back in the city on Wednesday evening, when he is expected to attend a campaign event.
