Crossover Voting

The term crossover voting refers to voters who traditionally vote for one political party crossing over during a primary election to vote for a candidate from another political party, either due to dissatisfaction with their own party’s candidates or to interfere with the selection of the nominee for another political party.

Example:

During the 2014 primary election in the Virginia’s 7th congressional district, Tea Party candidate David Brat received support from the Democratic Party through crossover voters who were trying to remove one of the Democratic Party’s most powerful opponents in Congress and in Virginia.
