Michigan required parties to poll at least 154,040 votes for a statewide race this year, in order to qualify for a primary in 2018. Both the Working Class Party and the Libertarian Party had some statewide candidates who exceeded this total. The Working Class Party only had one statewide candidate, and she polled 224,106 votes for State Board of Education.

Libertarian statewide candidates who exceeded that number include Gary Johnson for President, and two Libertarian nominees for statewide educational posts.

Even without qualifying for a primary, the two parties would have been on the 2018 ballot in any case, but if their votes had been smaller, they would have nominated by convention.

No presidential primary will be provided for either party in 2020, even if they are still entitled to a primary for other office in 2020. Michigan presidential primaries are only given to parties that polled 5% of the nationwide presidential vote. The Reform Party in 2000 is the only Michigan party that ever had a presidential primary. That primary was won by Donald Trump, who was seeking the Reform Party nomination early in 2000.
