Cross-filing

In American politics, cross-filing (similar to the concept of electoral fusion) occurs when a candidate runs in the primary election of not only his own party, but also that of one or more other parties, generally in the hope of reducing or eliminating his competition at the general election. It was in effect in California from 1913 to 1959, when it was abolished, and has been used in other states, most significantly in New York and New Hampshire, where it is still in effect.
