Presidential candidates have always understood that in a close election, any big news story in the last weeks of a campaign could be enough to tip the contest in November. Now known as an “October surprise,” the news story might take the form of a scandalous revelation about a candidate, the outbreak of war or economic turmoil, or even a fake story planted by a political enemy.
As early as the 1840 election, New York Democrats in support of President Martin Van Buren waited until mid-October to accuse the Whig party of paying Pennsylvanians to vote in New York, a key swing state. A whig official even admitted to the scheme, but it wasn’t the bombshell scandal Democrats had hoped for. Van Buren still lost New York and the election.
