State law establishes the process by which party nominees are selected. Most states use primary elections, but some permit the parties to nominate their candidates through a caucus or convention. In the caucus system, party delegates elected in local voting district meetings decide on the party nominee. In some states, a convention narrows the field to two candidates if no candidate gets a set percentage of delegate votes at the party convention. The dynamics of winning a nomination in states with a caucus system are different from those in states with a primary. In a caucus system, having a grassroots organization or an intense appeal that can mobilize politically active, better-educated voters to attend a neighborhood meeting is essential for candidates.
