Living near the border, and listening to a lot of radio, I have become fond of the Canadian Broadcasting Corporation. Many news services offer a list at the end of the year of "Best of..." or "Most important..." or whatever. The CBC offers "Flameouts of the Year"; and you can vote:
www.cbc.ca/day6. Whatever rules there are, are flexible; but the list is for people who are to one degree or another, famous, and who, through their own efforts, fucked up so badly as to be considered flameouts.
Right now Lance Armstrong is in the lead, followed by "Canada's Mayors", a collective group of fuck-ups you have to have followed to understand. Also in the running are groups like "KONY 2012" who started out making a ton of money, and ended up running naked down the street in a drug-crazed frenzy. My personal favorite was Silvio Berlusconi, but you have to have followed European news a lot closer than most U.S. news services to understand why.
Among the entries who started strong, but came up short, was Donald Trump. What does it say about a man that he failed to make a strong showing as Failure of the Year?
