The Michigan Supreme Court has ruled in favor of RFK Jr.'s reinstatement on the presidential ballot.

• The Supreme Court of Michigan has ruled that former independent presidential candidate Robert F. Kennedy Jr. will be on the presidential ballot in the state.
• The appeals court decision that removed Kennedy from the state's ballot was overturned by the 5-2 ruling, despite Secretary of State Jocelyn Benson's objections.
• Polling averages show that Vice President Kamala Harris maintains a lead over Republican nominee Donald Trump in the state, regardless of the number of candidates. However, her advantage decreases when the race is a direct matchup between the two.

The Supreme Court of Michigan ruled on Monday that former independent presidential candidate Robert F. Kennedy Jr. will be on the ballot in November, which could positively impact the national campaign of Democratic nominee Kamala Harris against GOP nominee Donald Trump.

On Friday, the Supreme Court reversed the decision of the state's Court of Appeals, which had removed Kennedy from the state's ballot despite the opposition of Michigan Secretary of State Jocelyn Benson.

On Monday, the high court made a majority decision to keep Kennedy's name on the ballot, as implied by the text of the order, even though the decision was unsigned and only five of the seven justices who considered the case voted in favor of it.

Despite being the vice president, Harris's lead over Trump in Michigan polling averages is reduced when compared to a head-to-head matchup.

After Pennsylvania, Michigan has the second-highest number of swing state votes in the Electoral College, which determines the winners of U.S. presidential elections, with a total of 15 votes.

Kennedy announced on Aug. 23 that he would suspend his campaign and support Trump, stating his intention to remove his name from ballots in swing states, including Michigan, to aid Trump's campaign.

Kennedy, nominated by the Natural Law Party in Michigan, filed a lawsuit against Secretary of State Benson after his request to remove his name was rejected.

In her decision, Benson referenced Michigan law, stating that candidates who accept a nomination as a minor party cannot withdraw from an election.

The Michigan Supreme Court ruled on Monday that Kennedy did not have a legal right to withdraw his name from the ballot, as he had not cited any law that defined this duty.

In its ruling, the court majority stated that "Kennedy has not demonstrated a right to this exceptional remedy."

The two dissenting justices, Brian Zahra and David Viviano, argued that by keeping Kennedy on Michigan's ballot, the Secretary of State is unjustly and unnecessarily depriving voters of the opportunity to choose between two candidates who are willing to serve if elected.

The dissenters emphasized the importance of the majority ruling in determining the outcome of the presidential race in their final statements.

The Court's endorsement of the Secretary's misguided action may have national consequences, they warned.

In addition to Virginia, Wisconsin and North Carolina also rejected Kennedy's plea to be taken off the ballots in those states.

In those two other states, officials were sued by Kennedy to remove his name from their ballots, as in Michigan.

On Friday, the North Carolina appeals court ruled in favor of Kennedy, preventing the state's election officials from mailing out ballots with his name as they had originally planned.

On Friday, Paul Cox, the general counsel for North Carolina's elections board, informed county election directors that no decision has been made on whether the ruling will be appealed.

A judge has yet to rule on Kennedy's lawsuit in Wisconsin.

In a head-to-head race against Trump, Harris' polling leads in Michigan, North Carolina, and Wisconsin have either decreased or she has fallen behind him, according to RealClearPolling.

In four battleground states - Pennsylvania, Arizona, Nevada, and Georgia - Kennedy successfully withdrew his name from ballots.

In Georgia and Nevada, a two-way race may boost Harris's prospects, not Trump's.
