Campaigning
The major parties select their presidential nominee at their national
conventions, held every four years. At the conventions, delegates from each
state vote and whichever candidate wins a majority of delegates becomes the
party’s nominee. To win delegates, candidates compete in primary elections, held
in each state prior to the convention. Primary races are usually hotly
contested.
Because citizens get to vote in the primaries, they have a large role in
the election. Prior to the 1972 election, voters played little role in selecting
the party nominees, but that is not the case anymore. Before acquiring the party
nomination, a presidential candidate must prove that he or she can attract
voters by winning primaries.
