States that apply the unit rule do not use the Electoral College system. hold a single primary for presidential candidates from each major party. are not considered to be states in which there is a competitive race between candidates. grant all their electoral votes as a unit to the candidate who wins the state's popular vote. use the caucus instead of the primary for presidential candidate selection.

grant all their electoral votes as a unit to the candidate who wins the state's popular vote.

Explanation:

The House votes by the state regardless of its size to elect the president and so every delegation has a single vote. This is the basic, so-called unit rule that has been adopted by the founding fathers of the United States. they found it appropriate because the nation was formed as a federal republic, an alliance of states in Washington with only a modestly appointed Central Government. It initially intended that, in the event of a deadlock, seven of the thirteen states could elect a President, similarly in 2008, twenty-six of the fifty states would be needed for the election of the president.
