American meddling in elections
Italy's 1948 general election is an early example of a race where U.S. actions probably influenced the outcome.
"We threw everything, including the kitchen sink" at helping the Christian Democrats beat the Communists in Italy, said Levin, including covertly delivering "bags of money" to cover campaign expenses, sending experts to help run the campaign, subsidizing "pork" projects like land reclamation, and threatening publicly to end U.S. aid to Italy if the Communists were elected.
Levin said that U.S. intervention probably played an important role in preventing a Communist Party victory, not just in 1948, but in seven subsequent Italian elections.
