A nonpartisan blanket primary is a primary election in which all candidates for the same elected office run against each other at once, regardless of the political party. Partisan elections are, on the other hand, segregated by political party. Nonpartisan blanket primaries are slightly different from most other elections systems with two-rounds/runoff, aka "jungle primaries" (such as the (Louisiana primary),in a few ways. The first round of a nonpartisan blanket primary is officially the "primary." Round two is the "general election." Round two must be held, even if one candidate receives a majority in the first round.
