Libertarian Party candidate Gary Johnson has officially qualified for the Iowa ballot.

Two Iowa voters had challenged his candidacy last week and Jay Kramer, a Romney campaign staffer, signed as a witness the challenge that Libertarians’ convention at the Iowa State Fair wasn’t real.

Republican Secretary of State Matt Schultz, Democratic Attorney General Tom Miller, and Warren Jenkins, the chief deputy for Republican Auditor David Vaudt, said Iowa’s law on holding conventions to get on the ballot is vague and they opted to err on the side of open ballot access, the AP reported.

Mr. Johnson told The Washington Times Tuesday that he is going to be the only third-party candidate this year to get on the ballot in all 50 states.
