It could be the only day before the Nov. 6 election without explicit partisan rancor.
Both President Barack Obama and Republican challenger Mitt Romney plan to take down their negative ads in honor of the 11th anniversary of the 9/11 terrorist attacks.
Neither plans to appear at overtly political events, although Election Day is never far from their agendas.
Obama has scheduled a moment of silence at the White House and a trip to the Pentagon, the target of one of four planes al-Qaida hijacked 11 years ago.
Romney is set to address the National Guard. His running mate, Rep. Paul Ryan of Wisconsin, hasn't scheduled any public events.
Vice President Joe Biden is expected to attend a memorial service at Shanksville, Pa., where a hijacked airliner crashed on 9/11.
