General Elections - an election to fill public offices.

Primary Elections - an election prior to the general election in which voters select the candidates who will run on each party's ticket. Primaries are also used to choose convention delegates and party leaders, and may be open or closed.

Open Primary - an election that permits voters to choose on Election Day the party primary in which they wish to vote. They may vote for candidates of only one party. (A blanket or "free love" primary is a type of open primary. In the voting booth you mark a ballot that lists the candidates for nomination of all the parties, and thus you can help select the Democratic candidate for one office and the Republican candidate for another.)
Closed Primary - the selection of a party's candidates in an election limited to registered party members. Prevents members of other parties from "crossing over" to influence the nomination of an opposing party's candidate.
Runoff Primary - if no candidate gets a majority of the votes, a runoff is held to decide who should win.
Presidential Primary - a primary used to pick delegates to the presidential nominating conventions of the major parties.
