Answer:
The Bradlye effect occurs when people say they will vote for a candidate but then vote against him or her.
Explanation:
The Bradley effect is a political theory that seeks to explain the behavior of voters in U.S. when there is a non-white candidate going against a white candidate. It states that when being asked in the polls for which candidate they are going to vote, white voters tend to say they are going to vote for the non-white candidate, because they think that is a politically correct response, but on the elections they will vote for the white candidate.
This theory has been formulated after several local and state elections where there was a black candidate that was leading substantially in the polls and lost the elections.
