Cindy McCain, widow of the late Sen. John McCain, formally endorsed Joe Biden for president on Tuesday night, saying she would participate in virtual campaign events and in person when Biden visits her home state of Arizona. McCain's support for Biden doesn't come as an enormous surprise given the video about her husband's relationship with Biden she narrated for the Democratic National Convention, but her plan to be involved in the campaign is another serious step.

"The most important thing that moved me a great deal was talking about troops' being 'losers,'" McCain said of her endorsement. "You know we have children in the military, as did the Bidens." The man who called the troops losers and suckers for getting captured or killed in combat responded with predictable grace.
