Discussing the possible move late last month, Johnson told KOB Eyewitness News that the party had been unwilling to help him get included in the debates or polls.
"From what I see and hear on the ground, I think a lot more people embrace this message than not, and the Republicans certainly aren't even letting me be heard," Johnson said.
But Johnson believes his message could be better championed as the Libertarian candidate.
"The message wouldn't be changing at all," Johnson said. "It's just a message that hasn't gotten heard. Really, I feel pretty put off by the process and by Republicans not standing for me … just being in the polls to determine whether or not I should be in the debates or not."
Michigan's secretary of State told the Detroit Free Press Wednesday that Johnson would remain on their Republican ballot, along with Herman Cain, who dropped out of the race after allegations of sexual impropriety surfaced.
