On August 5-6, the Michigan Green Party, which is ballot-qualified, nominated its candidates. Doug Campbell was nominated for Governor, and David Sole for U.S. Senator.
There are twelve U.S. Senate races this year that are considered somewhat competitive. Of those, Greens have nominated a candidate in Maryland, Michigan, Minnesota, Pennsylvania, Tennessee, Virginia, and Washington. They have not done so in Missouri, Montana, New Jersey, Ohio, and Rhode Island.
Although the Green Party that is on the ballot in Virginia is not affiliated with the national Green Party, it is the only Green Party that is on the Virginia ballot this year.
Democrats are furious with the Green Party for running someone for U.S. Senate in Pennsylvania, but seem to have nothing to say about the Greens running in six other close Senate races.
