"Bob Casey is building up a war chest bankrolled by the most extreme liberal special interest groups in the country. Pennsylvania deserves better than an obstructionist senator," Barletta says in the video. "But I want to offer Pennsylvania more than just being a better option than Bob Casey. I want to be the type of senator that you can be proud of, confident that I will always put Pennsylvania's interests first, and assured that I will work relentlessly to give Pennsylvania a strong voice in Washington."
