On May 9, Robert F. Kennedy, Jr., qualified for the November ballot in Oklahoma, by paying the huge filing fee of $35,000. See this story.
The filing fee alternative to a petition has only existed in Oklahoma since 2017. In the 2020 presidential election, three candidates paid the fee: Kanye West, Brock Pierce, and Jade Simmons, all of them independents. The law applies to unqualified party presidential nominees also.
Qualified parties are on the ballot automatically without the need for the fee. Oklahoma has three qualified parties: Republican, Democratic, and Libertarian. The Green Party hopes to use the filing procedure this year. If they do, the party label “Green” will be on the ballot next to the presidential candidate’s name.
