Dewey defeats Truman 2010?
From Bob Powers at the Boston Globe, regarding the little oopsie I tweaked them for earlier:
[Associated Press] was testing an election data feed to its Massachusetts clients.
During corresponding tests at our end, the feed of AP's hypothetical test
data was inadvertently posted for a few minutes on a single subsection page
within our site. As soon as the error was discovered, it was removed. We
regret the mishap.
