LANSING, Mich. (Michigan News Source) – Perry Johnson, one of the GOP candidates bounced from the August 2 primary ballot for invalid petition signatures, says he will consider a write-in campaign if a federal court does not rule in his favor.

Johnson filed a lawsuit on Monday. He is asking the court to order Michigan to stop the printing of ballots and “decrease the signature threshold requirements or place Mr. Johnson’s name on the … ballot.”

“I am still hopeful that we will win this case,” Johnson told “The Steve Gruber Show” on Wednesday morning. “[A write-in campaign] is something I will have to look at in the event I do not win this.”

Johnson is one of five GOP gubernatorial candidates barred from Michigan’s primary ballot for invalid or insufficient signatures.
