- Colorado, Connecticut, Massachusetts, New Mexico, New York, North Dakota, and Utah parties conduct conventions prior to their primaries that can impact primary ballot access.
- Iowa parties condcut conventions to select nominees if no candidate receives over 35 percent of the vote in the primary.
- Minnesota parties conduct conventions after which candidates who fail to win their party’s endorsement often (but by no means always) drop out.
- Virginia parties, at their discretion, may select nominees at conventions rather than via primaries.
- Primary runoffs between the top two vote-getters are required in some states if no candidate receives over a certain threshold of the vote in the primary:
- 30 percent in North Carolina;
- 35 percent in South Dakota; and
- 50 percent in Alabama, Arkansas, Georgia, Louisiana, Mississippi, Oklahoma, South Carolina, and Texas.
- Georgia conducts a runoff between the top two vote-getters for state races on Dec. 4 and for federal races on Jan. 8, 2019 if no candidate receives a majority on Nov. 6.
- Louisiana conducts a runoff between the top two vote-getters on Dec. 12 if no candidate receives a majority on Nov. 6.
- Mississippi will conduct a runoff between the top two vote-getters in its special election for the Senate on Nov. 27 if no candidate receives a majority on Nov. 6.
- All filing deadlines on the calendar above are for major-party candidates and only apply to federal and statewide races unless noted below. Independent and third-party candidates, or contests for other races, may be subject to different deadlines.
-
California's filing deadline is extended to March 14 in races where eligible incumbents (i.e., excluding term-limited incumbents) do not file for re-election.
- Florida’s filing deadline for state candidates is June 22.
- Massachusetts requires candidates to file with local election officials on May 8, then requires them to file again with the secretary of the commonwealth on June 5. The first step is therefore necessary but not sufficient for candidates to appear on the ballot.
- Nebraska’s filing deadline for incumbents, regardless of whether they are seeking re-election or another office, is Feb. 15.
- New York's state and local primaries will take place on Sept. 13. The filing deadline is July 12.
- Pennsylvania’s filing deadline for U.S. House candidates was moved to March 20 because of court-ordered redistricting.
