The correct answer to this open question is the following.
A Primary election is an election held within each of the two major parties—Democratic and Republican—to pick its candidates for the general election. This is the method most commonly used today to nominate candidates for office.
Commonly known as primaries, a primary election is the type of election where voters gather to reveal their favorites and elect a political candidate. After the primary, the pool of candidates is reduced. This can be done in an open primary, where all the public can vote, or a closed primary, where just the members of the political party can vote. We are about to see exactly this with the Democratic Party in order to decide who is going to be its official candidate for the 2020 election. As you have seen, today, there are 7 or 8 candidates, being Joe Biden the front runner.
