The Republican, Democratic, and Libertarian Parties all have nominees on the ballot for Pennsylvania’s U.S. House race, 7th district, in the Lehigh Valley. At least four debates are being held that include all three candidates. See this story.

Last month, the Republican Party executive director, Mike Stoll, wrote a letter to the Pennsylvania Attorney General, saying he had found two voters whose signatures were listed on the Libertarian petition and who now say they didn’t sign the petition. The objection was dismissed. The Libertarian, Tim Silfies, submitted 2,250 signatures to meet a requirement of 1,019 signatures. Silfies told the press that many individuals who had signed his petition received phone calls from unidentified individuals, asking if they had signed his petition. The 7th district is considered a swing district.
