Answer:
The voter is said to vote a split ticket.
Step-by-step explanation:
Split ticket voting occurs when a voter chooses to vote candidates from different political parties into different offices in the same election.
An example is voting a Republican as President of the United States, and in the same election, going ahead to vote a Democrat into the Senate.
A voter may choose to do this for any number of reasons, one of which may include trying to ensure a check and balance on the power of the presidency.
