From the Associated Press via the Pittsburgh Post-Gazette:
All three Libertarian Party nominees for statewide office in Pennsylvania abandoned their bids for the fall ballot today, leaving no third-party opposition to the Republican and Democratic candidates for governor and U.S. Senate.
Filing papers to withdraw were York lawyer Marakay Rogers, a perennial candidate who was running for governor; political newcomer Douglas Jamison, an engineer running for Senate; and Kat Valleley, a Bucks County homemaker seeking to become lieutenant governor. The action followed nearly two days of intensive scrutiny of their petition signatures.
The reason for the withdrawal is made quite clear by Ballot Access News.
They were told that if they didn’t withdraw, and the challenge showed that they don’t have enough signatures, their costs would be between $92,000 and $106,000.
Along with Green Mel Packer in the US Senate race, the Libertarian candidates will still wage a write-in campaign. Still, watch out for local Libertarian candidates for Congress and state legislature that remain on the ballot, as Pennsylvania does have several active local Libertarian affiliates.
