Every four years the American election season culminates in November, when voters select a new president. But the process begins a year, sometimes two, before the actual election as candidates compete to become the nominee for their party.

The nominees are selected in a complicated series of voting contests known as primaries and caucuses. After that, the Republican and Democratic parties hold national conventions, where they formally nominate their candidates and the final race for the White House begins.
