On July 10, Indiana county election officials announced they had certified around 39,000 petition signatures to place the independent candidate on the state's general election ballot.

That same day, through the We the People Party, Mr. Kennedy said he turned in the required number of signatures to get on the ballot in Georgia.

The campaign also announced that the New York State Board of Elections determined the candidate submitted 108,680 valid signatures for ballot access in that state, more than double the 45,000 required.

On July 11, Mr. Kennedy's campaign announced it had submitted enough signatures to gain ballot access in Colorado. The campaign turned in more than 30,000 signatures, more than double the 12,000 required, according to a statement.

Last week, the Libertarian Party of Colorado (LPCO) nominated Mr. Kennedy as its presidential candidate, though the national party selected Chase Oliver at its national convention in May.

"We hope to place RFK Jr. on two ballot lines in Colorado, where in the tradition of fusion voting, Coloradans will see him running as an Independent and with support from the Libertarian Party of Colorado," LPCO Chair Hannah Goodman said in a statement.

The Kennedy–Shanahan ticket is officially on the ballot in nine states: California, Delaware, Hawaii, Michigan, Minnesota, New Mexico, Oklahoma, South Carolina, and Utah.

The campaign has submitted signatures for ballot access in Alaska, Colorado, Georgia, Illinois, Indiana, Nebraska, Nevada, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, and Washington.

The ticket has also collected enough signatures for ballot access in Florida, Idaho, Iowa, Mississippi, New Hampshire, and Nevada.
