HARRISBURG, Pa. -

The Libertarian Party has won a round in the drawn-out challenge of its nominating petitions in Pennsylvania, even as its presidential candidate prepares to visit the state.

Gary Johnson, a former Republican governor of New Mexico, will begin a national tour of college campuses Monday at West Chester University. The Libertarian Party standard-bearer plans to speak and answer questions from the audience.

A three-judge panel of the state Commonwealth Court ruled 2-1 on Thursday that signatures of about 9,000 voters are valid even though they listed addresses that do not match those in the statewide voter registry.

Challengers backed by the Republican Party argued at a hearing this week that those signatures should be disqualified, which could have knocked Johnson off the statewide ballot.
