Ed Straker has this list of states in which non-Republicans can vote in Republican presidential primaries and caucuses. The list differentiates between open primaries and semi-closed primaries. In open primaries, any voter can choose any party’s ballot. In semi-closed primaries, independents can choose any party’s primary ballot, but members of parties other than the Republican Party cannot.

Straker’s list has 26 states. However, the list appears to be wrong about Arizona and Oklahoma. Independents cannot vote in the Republican presidential primary in Arizona, not any Republican primaries in Oklahoma. If a similar list for Democrats were compiled, it would include California, Nebraska, Oklahoma, and South Dakota.

Rocky De La Fuente has criticized the Georgia Democratic Party for not putting his name on the Georgia Democratic presidential primary. See this story. Georgia and Florida are the only two states in which there is no way to get on a presidential primary ballot if the state party leaders choose not to list the candidate. See this story.

Oddly enough, the Georgia Democratic Party did list Michael Steinberg. Steinberg will be on the ballot along with Hillary Clinton, Martin O’Malley, and Bernie Sanders. Steinberg is only on the ballot in four other Democratic presidential primaries, far fewer than De La Roque.

The Georgia Republican ballot will include Jeb Bush, Ben Carson, Chris Christie, Ted Cruz, Carly Fiorina, Lindsey Graham, Michael Huckabee, John Kasich, George Pataki, Rand Paul, Marco Rubio, Rick Santorum, and Donald Trump. This list of 13 Republicans was finalized on December 17, before Graham and Pataki withdrew. It does not include Jim Gilmore, even though he has not withdrawn.

In 1992, David Duke, who was running in Republican presidential primaries, sued Georgia and Florida over those states’ laws that let no method to get on a presidential primary ballot for candidates not chosen by the state party leaders. However, he lost both lawsuits.

Here is the list of presidential primary candidates in Missouri. The primary is March 15. Candidates qualified by paying a fee of $1,000. There are twelve Republicans, nine Democrats, and five Libertarians.

The only prominent major party candidate who did not file is former Virginia Governor Jim Gilmore, a Republican.

Missouri is the first state so far in which filing has closed for a Libertarian presidential primary. In 2012, the only person who filed for the Libertarian presidential primary was James Ogle. He received 483, and uncommitted received 431.

The five Libertarians who filed for the 2016 primary are: Marc Allan Feldman of Ohio, Cecil Ince of Missouri, Steve Kerbel of Colorado, Austin Petersen of Missouri, and Rhett R. Smith of Texas.

No one filed in the Constitution Party’s presidential primary.
