FILE - In this Sept. 1, 2018, file photo, Cindy McCain, glances back towards the hearse carrying her husband's casket, following a memorial service for her husband Sen. John McCain, R-Ariz., at the Washington National Cathedral in Washington. A nonprofit named for the late Sen. John McCain is calling for “mavericks” like him to vote in the Nov. 6 election and focus on human rights around the world. The McCain Institute for International Leadership, led by his widow, Cindy, is launching a nonpartisan campaign Tuesday, Oct. 23, to spread that message especially to young Americans.
