Alex Okrent, a 29-year-old member of the campaign's ad-buying team, collapsed and died yesterday of unknown causes. This prompted public condolences from Obama himself and Mitt Romney — to which David Axelrod responded: "@MittRomney Thank you, governor. Alex was a beloved member of our team. It's been a very emotional day." Unfortunately (but not surprisingly), certain other online elements were less respectful, leading the Chicago Sun-Times to turn off comments after trolls began mocking the death as a political stunt.
